Lloyd was the first man to hold the magnificent gold World Cup trophy
The inaugural World Cup was universally termed a great success, not a ball was lost to the weather and fittingly there was a captivating final instalment at the home of cricket.
It was the longest day, 21 June, and Lord's was bathed in warm summer sunshine as umpires Dickie Bird and Tom Spencer took to the hallowed turf.
A large throng of fervent West Indian supporters had enriched the tournament wherever their team played and were in force again for the final against Australia.
Australia were thought to be more focused on the Ashes series that followed, although that is a view that may well have eminated from down under after the event.
One-day cricket was still relatively unknown in Australia and Ian Chappell asked Clive Lloyd's West Indies to bat first when he won the toss, under the old adage "We'll see what you get first".
Unlike subsequent Lord's finals, moisture in the wicket was not a significant factor, given the hot conditions and the 1100am start.
There were no team colours, both teams wore white and a conventional red ball was used, with the matches played on a 60-overs per-side basis.

There was an eventful start to the proceedings when West Indian opener Roy Fredericks hooked fearsome paceman Dennis Lillee out of the ground, only to tread on his wicket in the process.
Chappell opted to let burly left-arm seamer Gary Gilmour share the new ball and the decision paid dividends as he dismissed left-hander Alvin Kallicharan cheaply, the first of his five wickets.
Jeff Thomson, then a raw 24-year-old, was brought on as first change and promptly accounted for Gordon Greenidge to make the score 50-3.
But that brought in Lloyd, and the powerful skipper duly chose the big stage to play a match-winning innings, smashing 12 fours and two sixes in 102 from 85 balls, sharing 149 with Rohan Kanhai who made a rather more subdued 55 off 108.
Wicket-keeper Deryck Murray, batting at number nine, hit a six and a four in 14 from 10 balls to boost the West Indies total to 291-8 from their allocation.

While the Australian fielding was somewhat lax, the West Indies were very sharp, with Viv Richards having a hand in three of five run-outs.
Chappell threatened to match counterpart Lloyd with a century, but on 62 he chanced his arm to Richards, who sent the ball whistling in for his captain to remove the bails.
Keith Boyce claimed three wickets to leave the Windies on the brink of victory, before Lillee and Thomson combined with the bat rather than the ball, blasting a final wicket stand of 41 from only six overs.
With the light closing in, Murray kept a cool head with his underarm throw to run out Thomson and secure a 17-run success for the Windies as the famous Lord's clock nudged towards 8.45pm.
