Bolt, perhaps the biggest star of the London Games, hotfooted it from the Olympic Stadium on Saturday night to a party nearby in east London and turned DJ to entertain the packed crowd.
"He came on stage and grabbed the mike," DJ Manny Norte told The Associated Press on Sunday. "The energy went up ten fold — it was electric. Everyone was very excited to see him."
He proved a match for the professionals at a packed club that's been Jamaica's Olympic party base.
"It was a historic event," said Norte, who performed alongside Bolt. "It's not every day you get to play to a crowd with the fastest man on planet ... you can tell he loves his music — his pop and reggae. We mixed up the tracks at bit."
That's after Bolt proved himself on the track in London — again.
The Jamaican defended the gold medals in the 100 and 200 metres and the 4x100 relay that he won in Beijing.
"I am happy and I did what I did and I came here to be a legend," Bolt said at the party. "I am now, so I am very happy with myself."
He is the only athlete to win gold in the sprints in consecutive games.
"It is a wonderful feat," he said, between posing for pictures and feasting on Jamaican food with his teammates. "We always come out here and give it our best.
"At the last Olympics we did great and at this Olympics we did great, so for me, it was an honour to share it with these guys and to do wonderful things and extraordinary things — so for me, I am very happy."
After attending his sponsor's party in East London's Brick Lane neighbourhood, Bolt dashed to a glitzier nightclub, Movida, in London's West End.
Club spokeswoman Martina Pokorna said the group included Bolt's teammate Yohan Blake and British swimmer Rebecca Adlington.
She said they were given a Nebuchadnezzar — the equivalent of 20 bottles — of Ace of Spades champagne. It has a retail price of 80,000 pounds ($125,000).
"They left at 6 o'clock this morning," she said.
