From Shakin' Stevens to Jay-Z via James Blunt, Amy Winehouse and many more, Glastonbury's main stage had one of its most eclectic ever line-ups on Saturday.
Who got the thumbs up from the crowd, and who sank in the mud?
BBC News music reporter Ian Youngs was in front of the Pyramid Stage, supplying regular updates, below.

SUNDAY, 29 JUNE - 0100 LOCAL TIME (0000 GMT)
The reception Jay-Z received makes the pre-show controversy about whether a rap star should headline the festival look faintly quaint and ridiculous.
He carried most of the crowd with him for the full show, with the Pyramid Stage field a sea of waving hands during his hit Hard Knock Life near the end.†
It was by far the best reception of the day.†
And it was much more exciting than just another Coldplay or Radiohead slot would have been.†
SUNDAY, 29 JUNE - 0010 LOCAL TIME (2310 GMT)
Jay-Z certainly knows how to work a crowd.
Whether it's asking them to put their hands in the air, sway in time or just scream, he has them eating out of his palm.
SATURDAY, 28 JUNE - 2330 LOCAL TIME (2230 GMT)
The crowd seems to be a bit thinner for Jay-Z than for Amy and a few people seem to have left after seeing what all the fuss was about.
But those that are here are having a real blast and he's getting a better reception than Amy.
This is the first time the Glastonbury crowd has been told to "put your diamonds in the air".
SATURDAY, 28 JUNE - 2300 LOCAL TIME (2200 GMT)
The argument is already over, and Jay-Z has won.
He came on stage to strains of Noel Gallagher saying hip-hop was "wrong" for Glastonbury, but got an ecstatic reception from the crowd.
They were chanting his name before he played Oasis' Wonderwall and then his biggest hit 99 Problems.
They're chanting his name again now....
SATURDAY, 28 JUNE - 2245 LOCAL TIME (2145 GMT)
Well, she's never dull.
Amy Winehouse played the last two songs in the security pit, teetering on - and falling off - a ledge right in front of the crowd.
There was confusion as Winehouse appeared to lunge into the crowd
There was a flashpoint when she appeared to lash out at a member of the audience. I didn't see what provoked it.
That was the return of the shambolic Amy. She also had to cut two songs, including Valerie, because she overran.
I tried to go for a walk around the crowd during the set but gave up after about 20 metres because it was too packed.
Waiting for Jay-Z, the crowd has thinned out considerably.
SATURDAY, 28 JUNE - 2130 LOCAL TIME (2030 GMT)
Is this really the same Amy Winehouse we know from the papers? The dangerous wreck who's in danger of throwing it all away?
Not tonight she isn't. She's engaging, in good voice and not looking too bad for someone who's only been let out of hospital for the night.
She hasn't had any trouble keeping the party atmosphere alive, with loud screams from the crowd after every song.
I get the feeling they're glad to be able to connect with woman herself in the flesh, and her songs, without any of the other personal rubbish getting in the way.
SATURDAY, 28 JUNE - 2130 LOCAL TIME (2030 GMT)
After all the speculation and uncertainty, Amy Winehouse is actually here.
And she appears to be on form.
Troubled star Winehouse appeared to be on good form, Ian Young says
She is talking, joking, dancing, looking every inch the superstar, with not a worry in the world.
There was a huge cheer as she came on.
She started with her song Addicted
This was followed by Just Friends, and of course both of those tracks were from her most recent album, Back to Black.
SATURDAY, 28 JUNE - 2050 LOCAL TIME (1950 GMT)
It's not often that you see people properly dancing from the front of the Pyramid Stage field to the back - let alone to an artist many of them may never have heard before.
Franco-Spanish singer Manu Chao has really got the party started.
French-born singer of Spanish origin Manu Chao wowed the festival crowd
He seems to have combined the world's most infectious and incendiary styles - punk, reggae, west African beats, flamenco and hip-hop (not all in the same song, but almost).
The end result has a super-fast, super-catchy rhythm that gets hips and feet moving.
Chao himself has an urgency to his voice and presence, regularly thrusting his right arm into the air, urging the crowd to bounce up and down and generally with a strained expression on his face, that it's hard not to get carried along.
I had no idea what he was singing about most of the time but it must have been something to do with loving each other, saving the world and generally starting a revolution.
After such a feelgood performance, the question is - how will Amy be able to follow it?
SATURDAY, 28 JUNE - 1935 LOCAL TIME (1835 GMT)
Jack White and The Raconteurs brought some good old-fashioned rock action to the Pyramid Stage after the brief coup by the pop batallion.
Jack and fellow frontman Brendan Benson soon got down to screeching and scratching, twanging and thrashing like proper 1970s-style Axe Gods, creating an almighty psych-out that intoxicated some in the crowd.
The Raconteurs were the latest act on Glastonbury's main Pyramid Stage
Lots†were grooving along, but not many were being blown away and the massed ranks behind the hard core of fans seemed to remain largely unconvinced.
The sun has stayed out and it is now a beautiful evening. Thank you to the Glastonbury Gods.
SATURDAY, 28 JUNE - 1730 LOCAL TIME (1630 GMT)
Right, listen up any James Blunt cynics, here is the news. Glastonbury loves James Blunt and he loves us.
He's actually a decent bloke, OK? He's one of us. He knows what we're going through. And he articulates it sensitively and elegantly in songs with good tunes.
I love James Blunt. There. I've said it.
It was hard not to be won over by his melodies and his charisma (yes, you heard me right).
He was more animated on stage than most performers here, jumping on top of his upright piano at one point and riding an imaginary wave.
James Blunt scored nine out of 10 on Ian Youngs' Glastometer scoreboard
During another song, he jumped down from the stage to hug most of the front row.
He also hunched over his piano and started headbanging, and then lifted up his polo shirt to expose his stomach, for no apparent reason.
All along, he was looking out to the crowd and beaming as if he was genuinely excited and pleased to be here.
And the crowd responded. Jay-Z, I hope you were watching and taking notes.
Two young ladies near me were sitting in their camping chairs, cigarettes in their hands, trying desperately to remain cool and disinterested.
But I'm sure I saw one wellington boot sway along to the music towards the end.
"Put your hands in the air and say sausages!" he told the crowd as he took a photo of them at the end.
What a nice bloke.
SATURDAY, 28 JUNE - 1615 LOCAL TIME (1515 GMT)
At last! The sun finally has finally broken through, just as Crowded House were playing their apt hit Weather with You.
The song got a languid crowd on their feet, and Neil Finn led a couple of Mexican waves†from the back of the field to the front.
They followed that with what could be another Glastonbury anthem, Four Seasons in One Day. Let's just hope summer sticks around for a little bit longer.
Crowded House led a Mexican wave among the crowd at the main stage
For now, T-shirts are coming off and suncream is coming out all over the site.
Crowded House played a couple of their other greatest hits, but their set was mostly made up of new material that was inoffensive, verging on the bland.
A good chance to kick back, chill out, read the paper, sleep off that hangover...†the perfect soundtrack for a Sunday afternoon...
Let's just hope James Blunt gets people in more of a party mood. Hmmm.
Glastometer - 9/10 for Weather with You, 6/10 for the rest
SATURDAY, 28 JUNE - 1400 LOCAL TIME (1300 GMT)
Old-school bluesman Seasick Steve was one of the surprise stars of last year's festival.
Wearing dusty dungarees, a grey beard and tattoos, he plays dirty, funky blues on battered guitars.
He takes swigs of Jack Daniels on stage and tells stories of being thrown through a closed window by his stepdaddy, riding freight trains and drinking on the porch in the summer.
The Glastonbury crowd "loved" Seasick Steve, Ian Youngs says
He plays a three-stringed guitar, but at one point produced a one-stringed guitar - basically a plank of wood with a string down the middle.
How he managed to make it howl and roar with such precision and power is beyond me.
At the end of the song, he threw it to the ground and it screeched as he rubbed it along the stage.
The crowd absolutely loved him. He is a hero here.
The Pyramid field has filled up now, with many people staking the spots where they will stay all day.
It is warm if cloudy, and I have decided to ditch my wellies for normal shoes. I hope I don't regret it.
SATURDAY, 28 JUNE - 1300 LOCAL TIME (1200 GMT)
US kook queen Martha Wainwright has a hard core of fans.
However most people are just lounging on the ground (a mixture of dry mud and trampled grass) and soaking up the atmosphere.
Martha Wainwright has broken a habit and is not camping this year
The Pyramid Stage is "downtown Glastonbury", she says, telling fans she's been to the festival five or six times before and always camped near the stone circle.
But she goes and ruins it by admitting she's in a tour bus this year.
"I'm sorry. You'll be fine," she says, unconvincingly.
SATURDAY, 28 JUNE - 1145 LOCAL TIME (1045 GMT)
There is a big crowd for Shakin' Stevens, the first act of the day, and some fans have obviously been getting very excited.
One sign in the crowd simply says "Shakin' Stevens Rocks Glastonbury", while elsewhere five friends are each holding a giant letter to form the word Shaky.
Some blokes have even brought a door - green on one side, naturally, with a message on the other.
He doesn't play Green Door these days, but when the Welsh Elvis strikes up This Ole House, with the sun breaking through, it is a classic Glastonbury moment.
Much hip-swivelling, jiving and general grooving ensues.
He plays a few other hits, such as Oh Julie and Marie Marie.
And he just about manages to keep the crowd on side when he utters the dreaded words: "We're going to do a few tracks from the new album."
