1700: Phew! That was bedlam! What a thrilling day of Scottish Cup action! Thanks again for your company. Bye for now.
Don't know about you but I'm off to spend my Saturday night at the Carthusian monastery of the Grande Chartreuse in the French Alps near Grenoble to wind down in complete silence, bar the odd bout of Gregorian chanting, with the monks of St Bruno. One sip of their famously heady liqueur and, like Baloo the Bear, I'll be gone, solid gone...
1659: Don't forget to tune in to BBC One Scotland tonight at 2215 for the highlight's from all of today's madcap Scottish Cup fourth round ties. Check out Artur Boruc aiming a kick at an imaginary ball...
1658: "Thank god! Aberdeen march onto the next round of the cup!" DenzilVoorhees on my Sport Join the debate
1657: "How come you said in the Somerset team news that Combe was unavailable for Kilmarnock through injury and then cited him for the failed clearance leading to the final equaliser? What's it to be: injured or playing a full 90 min?" Simpson on my Sport Join the debate
I got caught up in the excitement of Ayr's late equaliser and forgot that Mr Combe was out injured. I have since corrected my error and restored Rascle between the Killie sticks. I'm not sure if you noticed, but it has been a tad busy this afternoon, goal-wise etc. And I'm only human (or, as The Killers might ask, am I dancer?)!
1656: At long last the final whistle blows at Balmoor. Peterhead and Queen's Park will have to do it all again.
1654: Hamilton were reduced to 10 men in the dying moments of their victory over Ross County when James McArthur was given his marching orders for a second bookable offence.
1653: Airdrie, Aberdeen, Celtic, Dunfermline, Falkirk, Inverness, Hamilton and East Fife are through. Ayr will travel to Rugby Park for a replay after that amazing last-gasp leveller.
1652: Full-time all across the country now; except at Balmoor where Peterhead are still battling with the full force of mother nature, and Queen's Park. The sides are locked at 2-2.
1651: Full-time at the Caledonian Stadium - Inverness CT 3-0 Partick Thistle. I can see the headlines tomorrow, recycling an old nugget from the archives: 'Super Caley Go Ballistic the Weather Was Atrocious'
1650: Full-time at Celtic Park - Celtic 2-1 Dundee. The Parkhead club have won the Scottish Cup a record 34 times. They huffed and puffed a bit today but got the job done thanks to a wonderful goal from Aiden McGeady and you wouldn't bet against the Parkhead men going on to notch number 35.
1649: Full-time at Ochilview - Stenhousemuir 0-1 East Fife.
1648: Full-time at Somerset Park - Ayr United 2-2 Kilmarnock.
1646-and-a-half: Williams peels off his shirt, swings it above his head like an old-fashioned football fan's rattle and runs towards the touchline where he's embraced by a gaggle of team-mates. Williams, overcome with jubilation, hugs referee Steve Conroy. The ref books the giddy Ayr man who responds by ruffling the man in black's hair and planting a kiss on his cheek! Hilarious!
1646: Goal! Ayr United 2-2 Kilmarnock
Sensational scenes at Somerset Park! Killie keeper Damien Rascle desperately punches a corner clear, but only as far as Alex Williams who wellies a first-time volley through a ruck of players for an incredible equaliser.
1643: Goal! Stenhousemuir 0-1 East Fife
The visitors break the deadlock - and the gloom of a dismal game - in bizarre fashion when Bobby Linn's corner is picked up by a wicked gust of wind and buffeted across the line off the back post. Six minutes to go and East Fife appear to have snatched victory.
1640: "Why are Celtic playing today's game behind closed doors? Did one of their fans run on the pitch again." Jock-n-Jill on My Sport Join the debate
Cheeky monkey! Although I reckon there are only around 20,000 hardy souls who have braved the elements at Celtic Park today...you can't really blame the absentees..it's a day for curling up in front of a roaring fire with a hot toddy.
1638: Dundee's only Scottish Cup win over Celtic was back in season 1894/95. Well, Jocky Scott's men better get a move on or they could have a very long wait for another opportunity. It's been all Celtic and the score remains 2-1 to the home side.
1637: Goal! Falkirk 4-2 Queen of the South
Barrett taps home from inside the six-yard box. Is that former Pink Floyd front man Syd Barrett, risen from the dead with an Interstellar Overdrive strike? No it's Falkirk FC's Graham Barrett who sends his side into the draw for the fifth round of the Scottish Cup.
1636: Goal! Peterhead 2-2 Queen's Park
The home side shrug off the wild conditions to equalise against Queen's Park when Stuart Anderson fires home from 20 yards.
1635: Scott McDonald is about to pay for spurning a gilt-edged chance to bag Celtic's third goal and put daylight between the Scottish Premier League champions and their First Division opponents. Gordon Strachan has ordered little Japanese winger Koki Mizuno to strip for action.
1632: Michael Higdon's header crashes off the Queens bar and he then skies the rebound. BBC Radio Scotland's Chick Young emits a high-pitched squeal, as if he's had a certain body part slammed in a car door, at Higdon's absurd profligacy. It was his finger. That got jammed.
1627: An unbelievable stramash in the Killie box! There are arms, legs, bahookies, all manner of body parts flailing about in the mud trying to connect with the ball which is bobbing around the six-yard box like an elusive bar of soap.
1626: Killie miss a penalty! Allan Russell takes the spot kick but keeper Stephen Grindlay pulls off a great save. Grindlay has kept Ayr in this tie with a string of fine stops.
Killie had the chance to seal their place in the next round but Ayr have been handed a lifeline. This tie is still very much alive and kicking.
1624: Goal! Falkirk 3-2 Queen of the South
The Bairns take the lead for the first time in this topsy-turvy cup tie. Graham Barrett slams home from close range after Robinson saves from Darren Barr's shot.
1622: There's a barney at Somerset Park. Handbags at dawn as a cluster of players engage in a spot of pushing and shoving. It's getting tasty in a keenly fought Ayrshire derby with neither side giving any quarter. Frazer Wright gets a yellow card for his part in the affray.
1621: Nothing much to report from the only goalless tie at Stenhousemuir. Amid all this frenzied activity I'm almost hoping it stays that way...I could do with a pocket of calm in the eye of this hurricane of cup action.
1620: Michael Higdon heads wide of the Falkirk goal from Lee Bullen's cross. The Bairns are playing better against the howling gale. Sometimes that happens. Strangely, it can be easier playing into a tempest. The ball often runs away from players and passes go wildly astray with a strong wind at their backs.
1619: Goal! Airdrie United 2-1 Spartans
The East of Scotland League side pull a goal back when Gavin Malin's shot slips through the fingers of goalkeeper Stevie Robertson. Spartans are back in the game.
1617: Inverness CT 3-0 Partick Thistle
It looks like game over at the Caledonian Stadium. Andrew Barrowman heads the ball on for Filipe Morais to chase and the Portuguese midfielder knocks the ball into the net as defender Simon Storey slides in with a despairing challenge. It's hard to tell which player had the final touch.
1616: "Sone Aluko woop! Done blow the lead now ... please!" quigglesworth on My Sport Join the debate
The Dons are off the hook for the meantime. But there's a long way to go and it could still be squeaky bum time for the Two Jimmys...watch this space.
1614: Goal! Alloa 1-2 Aberdeen
A mazy run from Sone Aluko who gets in behind the Wasps defence and lobs Raymond Jellema to put the Dons back in front.
1613: Panting like a bespectacled hippopotamus after a few sausage suppers, portly Partick Thistle boss Ian McCall (of the Wild) is frantically scribbling down notes on the touchline as the visitors are drowning at the Caledonian Stadium.
1610: Goal! Ayr United 1-2 Kilmarnock
A hint of an own goal there as Craig Bryson's sizzling shot deflects off unfortunate Ayr defender Scott Walker. The sun ain't gonna shine anymore over Somerset Park.
1609: David Gormley goes agonisingly close to restoring the Honest Men's lead; his diving header flashes just past the post.
1607: Goal! Inverness CT 2-0 Partick Thistle
Don Cowie releases Iain Vigurs and the the young midfielder lashes an angled shot across keeper Jonathan Tuffy from just inside the penalty box.
1605: What an incredible start to the second half at the Falkirk Stadium! Queens had barely finished their goal celebrations when Arfield struck.
1604: Goal! Falkirk 2-2 Queen of the South
The Bairns draw level again with Scott Arfield driving home from the edge of the box.
1603: Goal! Falkirk 1-2 Queen of the South
BBC Radio 2 DJ 'Whispering' Bob Harris puts Queens into the lead with a stunning free-kick.
1602: Referee David Somers is going to play it by ear in the Peterhead v Queen's Park tie. If conditions don't improve at Balmoor in the opening 15 minutes of the second half then he will abandon the game.
1601: And we're away again!
1559: Managers of lower division clubs drawn against one of the big boys in the cup regularly limit their ambition to seeing their players give a 'good account of themselves.' Well, without jinxing anything, I'd say Alloa, Ayr, Dundee and Queen of the South are certainly doing just that...so far!
1557: Partick Thistle have never lost a Scottish Cup tie to Inverness; two draws and two replay wins. Well Ian McCall (of the Wild)'s side are playing catch up in the Highlands. They're trailing at the break to Filipe Morais' debut goal.
1555: Scotland's First Minister Alex Salmond is in the stand at Peterhead today. It's a local match for the grand fromage as he is the incumbent MP for the constituency of Banff & Buchan.
1553: After dominating the early stages, Aberdeen were on the ropes towards the end of that first half against Alloa. They're not happy chappies on that tricky plastic pitch.
1550: "Artur Boruc, again? When did he go from best keeper in Scotland to Calamity Jock?" MagnusMaximus on My Sport Join the debate
The Polish goalie took a wild swipe at fresh air to gift Dundee their opener. He's been guilty of a few howlers this season...
1546: Sorry for neglecting you all on My Sport. It's nothing personal; I've just been spinning plates trying to keep up with the avalanche of goals.
1545: Half-time all over the country! Phew! It's absolute mayhem out there. I'm going to retire to my hammock for the half-time break and fit in a quick power nap before the bedlam begins once more.
1544:Goal! Peterhead 1-2 Queen's Park Paul Cairney, who scored in last week's Division Two fixture between the sides, fires the visitors into the lead on the cusp of half-time.
1544: Goal! Celtic 2-1 Dundee
A flowing move culminates in Aiden McGeady cutting inside and sending a fizzing drive high into the back of the net beyond the helpless Rab Douglas. Great goal. Terrific comeback from Celtic.
1543: Goal! Airdrie United 2-0 Spartans
The home side double their advantage as Simon Lynch slides the ball home.
1542-and-a-half: Kilmarnock's Willie Gibson is causing Ayr all sorts of problems down the left wing but the match remains level.
1542: The Fifa website this week named Celtic's hyperactive midfielder Scott Brown as one of their players to watch in 2009. He's been enjoying a purple patch of form.
1541: Goal! Alloa 1-1 Aberdeen
Alloa had a goal disallowed and were immediately awarded a penalty. Slightly confusing! If the ref was playing proper advantage to Alloa then he would have let the original goal stand. Anyways,Andy Scott converts a delayed spot kick to equalise for the Wasps.
1540: Goal! Falkirk 1-1 Queen of the South.
Playing into a ferocious wind Barry Wilson's shot is deflected into the net off Lee Bullen.
1538: Goal! Celtic 1-1 Dundee
Scott McDonald's attempt at goal is thwarted and the ball rebounds into the path of a grateful Scott Brown who sweeps the ball home. Celtic are level.
1537: Goal! Falkirk 1-1 Queen of the South
Talented young whippersnapper Scott Arfield converts the resultant spot kick. The Bairns are back in it.
1536: Penalty! Moment of madness from Queen of the South. Falkirk are awarded a penalty after Graham Barrett's shirt is pulled by Craig Barr. Diddy behaviour from the Queens defender.
1534: Goal! Peterhead 1-1 Queen's Park James Brough makes amends for his earlier error that led to Peterhead's goal when he rises to power home a corner. With his head. It was a header. A powerful one.
1529: Goal! Inverness CT 1-0 Partick Thistle Filipe Morais marks his Inverness debut with a long range strike which takes a huge deflection off Marc Twaddle and flies beyond goalkeeper Jonathan Tuffy.
1528: Queens defender 'Whispering' Bob Harris blocks Graham Barrett's shot as the Bairns continue to threaten. The hirsute veteran former 'Old Grey Whistle Test' presenter is doing well for his age. Just kidding.
1527: Help! I can't keep up with the tsunami of goals.
1526:Goal! Airdrie 1-0 Spartans
Simon Lynch and Paul Di Giacomo play a neat one-two and the latter fires the home side into the lead over Spartans, who had just squandered a chance at the other end.
1523: Goal! Ross County 0-1 Hamilton
Accies take the lead after Chris Swailes heads home a Richard Offiong cross.
1522: "It's spelled Pascali! He isn't a squeaky voiced 'comedian.' And now Air have scored, I blame the spelling errors by Mr Chat." thebafosking on My Sport Join the debate
I know, I originally gave Killie's goalscorer's surname the same spelling as the hugely irritating helium-voiced 'comedian' Joe Pasquale. Thanks for spotting that. Otherwise, I haven't a scooby what you're havering on about...who is Mr Chat? Is that me?
1520: To recap on the Dundee goal: Boruc fluffed his attempt to volley clear a long ball towards the home penalty box and McMenamin passed the ball into the empty net.
1519: Goal! Dunfermline 1-0 Clyde Nicky Phinn puts the Pars ahead against Clyde. Not sure what happened. Will fill you in with more details as soon as the cameraman at the game wipes his lens to reveal the action behind the cascading rain.
1518: Aberdeen winger Sone Aluko has an effort cleared off the line as Alloa struggle to contain their vibrant SPL visitors
1517: Goal! Peterhead 1-0 Queen's Park
Peterhead, who have already had an effort cleared off the Queen's Park line, edge in front whenJamie Brough makes a hash of an attempted clearance and Martin Bavidge pounces to score.
1516: Goal! Celtic 0-1 Dundee
The Dens Park men take a shock lead through Colin McMenamin after a dreadful blunder by Celtic keeper Artur Boruc.
1515: Ayr United's Scott Walker somehow contrives to send a header narrowly past the post when it looked easier to score. Obviously, he's lost that scoring feeling.
1513: Goal! Ayr United 1-1 Kilmarnock
The Honest Men draw level through Dean Keenan who dives to meet Ryan Stevenson's perfect cross with a bullet header.
1510: It's all happening!
1509:Goal! Ayr 0-1 Kilmarnock
Killie bag their first goal against Ayr since 1994 as Manuel Pascali ghosts in at the back post and nudges the ball over the line with his thigh.
1508:Goal! Alloa 0-1 Aberdeen
The visitors take the lead within five minutes as Chris Maguire's strike ricochets off Lee Miller and wrong-foots Dundee keeper Raymond Jellema. If Miller claims that one, which he surely will, then its his eighth goal of the season.
1506: Ayr keeper Stephen Grindlay enjoyed that self-same run all the way to the Scottish Cup Final last season with Queen of the South...the only snag is he warmed his tush on the bench the entire time. That must be some kind of rubbish record!
1505: Queen of the South are without a win in the league since October. Perhaps they can banish their Division One blues and embark on another fairy-tale Scottish Cup run? Gordon Chisholm led his troops on a giddy road all the way to last year's Hampden final where they lost narrowly to Rangers.
1504: A minute later, Robinson tips Higdon's header over the crossbar.
1503: Falkirk striker Michael Higdon turns and shoots at the Queen of the South goal but goalkeeper Lee Robinson clutches the ball to his chest.
1501: The guy inside Ayr United's panda bear mascot is completely drenched with rain and must weigh about three tons. He trudges off the field of play and heads disconsolately down the tunnel: eats, shoots and leaves. He must feel like that guy who runs the London Marathon in a deep-sea diving suit.
1500: And we're off! On this occasion you will quite literally have to hold on to your hats, else they will be wheeched off by the hurricane gales!
1458: The rain is pounding down at Somerset Park as the players prepare to kick off.
1457: Teams from Celtic Park:
Celtic: Boruc, Caddis, Loovens, McManus, Naylor, Nakamura, Scott Brown, Crosas, McGeady, Vennegoor of Hesselink, McDonald. Subs: Mark Brown, Samaras, Robson, Caldwell, Mizuno.
1455: The Dons won't relish playing on Alloa's artificial surface. The pitch could prove to be the decisive factor in causing a cup upset.
Alloa knocked out second division leaders Raith Rovers at home in the third round thanks to midfielder Brown Ferguson's double. Despite the Wuthering Heights-esque wild wind and rain swirling around Recreation Park, there's not a single blade of plastic grass out of place.
1453: BBC Radio Scotland pundit Stevie Frail has been reminded by host Richard Gordon of the time he ran on as a substitute in the FA Cup for Tranmere against Sunderland, not realising that the player he was due to replace had just been sent off.
After several minutes of commotion, another player left the field to ensure Tranmere didn't avoid their punishment. Stevie admits that cup games were never his forte...
1448: For a team with the cup pedigree of Aberdeen they have a dismal record in recent years. The Dons have won the Scottish Cup seven times in their history and been runners-up on eight occasions. But they haven't won Scotland's premier knock-out tournament since 1990.
In fact they've not won ANYTHING since lifting the League Cup back in 1996. Of course, they were unceremoniously ousted from the Scottish Cup semi-final last season by Queen of the South; a result that manager Jimmy Calderwood described as the lowest moment of his Pittodrie tenure.
1447: Team news from Recreation Park:
Alloa: Jellema, McClune, Campbell, Buist, Townsley, Hill, Wilson, Brown Ferguson, MacAulay, Grant, Scott. Subs: White, Pat Scullion, Andrew Ferguson, Forrest, Spence.
East Fife: McCulloch, Nugent, Cameron, Smart, McDonald, Muir, Fagan, Templeman, McManus, Crawford, Linn. Subs: Brown, Stewart, Young, Campbell, McRae.
1444: Kilmarnock goalkeeper Alan Combe, who has agreed a new deal which keeps him at Rugby Park until 2011, is available again after suspension but misses the derby clash against Ayr with a neck injury. Damien Rascle deputises.
1442: Edinburgh's Spartans have twice reached the fourth round of the Scottish Cup, losing on both occasions to Livingston in 2004 and St Mirren in 2006. Will it be third time lucky for the side from the East of Scotland Football League against Airdrie United?
1440: The wind is blowing the rain horizontally across the New Broomfield pitch according to BBC Radio Scotland's Kheredine Idessane. I reckon the conditions will be similar all across the country this afternoon. Not the weather for silky football. The ball will be getting buffeted about like a giant ping-pong ball. It will be blow football on a grand scale.
1437: Clyde haven't won at East End Park since 1974. Looks like a home win there then today? Although, of course, like all today's mouth-watering cup ties, the eventual outcomes are in the lap of the gods.
I'm sure we're in for some twists and turns, thrills and spills, goals and gaffes. Let's get the banter going. Or as legendary sports commentator, Alan Partridge, a man whose drinks I couldn't lace, might say: why not hop aboard my chattanooga choo-choo? Join me: Join the debate
1434: "Predicting an upset for the Bairns at Falkirk. They haven't been great this season, and I'm sure Queen of the South will be out to prove the point that last year wasn't just luck!" meeks88 on My Sport Join the debate
1433: Strangely, Killie haven't beaten their Ayrshire rivals in 15 years! In saying that, the last time the sides played was over seven years ago. Ayr have triumphed on the last four occasions they've met.
1431: Danny Invincible returns for Kilmarnock and is thrown headlong into the Ayrshire derby against old foes Ayr United at Somerset Park
1430: Ross County will have a point to prove now that their opponents Hamilton are in the lofty heights of the SPL. The teams will know each other well from last season's First Division tussles.
1428: Early team news from Celtic Park: Aiden McGeady comes off the naughty step and is back in the Celtic starting eleven. The jinky winger has returned from a two-week suspension following a dressing-room bust-up with Strachan after last month's game against Hearts.
1427: Another great Strachan story: the Edinburgh-born Celtic gaffer almost signed for his local club Hibernian but allegedly knocked them back to sign for Dundee when the Hibs manager at the time Eddie Turnbull swore at Strachan's dad! Can we trace the beginnings of wee Gordy's dislike of so-called 'yob culture' to this moment in history?
1426: Did you know that when wee Gordon Strachan was even smaller than he is now - the size of one of 'The Borrowers' - he used to clean the boots at Dens Park? The Celtic boss started his illustrious playing career with Dundee.
Current Dundee boss Jocky Scott was a senior player at Dens Park when a tiny ginger kid arrived on Tayside in 1977. Despite his stature Strachan was soon mixing it up with the club's top players and Scott said he was so cheeky he came close to getting a clip round the ear.
1425: Afternoon all! Aaaaaah the magic of the cup! A whopping 10 Scottish Cup ties have survived the dastardly winter weather and we're all set for the Mother of all running commentaries.
As usual I want to hear all your rants and raves as the harem-scarem action unfolds.
