"Party, party, party" is the motto for the closing ceremony, according to Games officials, with a line-up of British and international performers set to dazzle the crowd.
Artistic director Kim Gavin says music will be the centrepiece of the two-hour and 45-minute show stopper, with the athletes placed in the centre of the stadium to create a "mosh pit".
"I want it to be a celebration, I want it to be fun, I want it to be colourful, and also remind you of certain eras of music collected over 50 years of popular music," he said.
"But not only popular music: fashion, culture. So I want it to be the best after-show party that's ever been."
Gavin's past credits include the Concert for Diana in 2007 and Take That's Circus Stadium Tour in 2009.
He has whittled down an original list of 1,000 songs to 30, with a 70-minute live set from a secret list of headline acts.
"I've called it the symphony of British music," he said.
"The ceremony will begin with an Elgar to Waterloo Sunset (The Kinks) day in the life of London. It's a very dense congested cacophony first 20 minutes."
But he has revealed that after the critical and popular acclaim of Danny Boyle's $40 million opener, some performers who initially declined returned wanting to get involved.
"We did have two actually but there was no room," he said, without mentioning names.
Comedy will also feature, as will the customary speeches which Gavin says will "hopefully be brief".
The show will wrap up with the ceremonial extinguishing of the Olympic flame and an almighty pyrotechnic display.
