Officials are trying to keep a lid on details for the Olympics Closing Ceremony but rumours abound about the acts who will perform at the musical extravaganza.
The show, which will air on Monday morning in New Zealand, is called "A Symphony of British Music", and organisers say it will feature everything from "Elgar to Adele".
Big names have been bandied around as speculation grows about who will actually perform, with some rumours seeming to be more substantial than others.
Rock band Muse are almost certain to play some part, having recorded the official track for the Games and telling music paper NME they will perform it at the ceremony.
George Michael has also jumped the gun by tweeting that he is "rehearsing like crazy" for the show, while ginger troubadour Ed Sheeran has also confirmed he will be taking part.
The English singer-songwriter, who performed in New Zealand a couple of weeks ago, told an Australian radio station he would be performing "Wish You Were Here" with at least two members of the legendary British rock band Pink Floyd. This has since been denied by Floyd themselves though.
Manchester indie darlings Elbow could have a role to play after recording an Olympics song for the BBC, while Jubilee show stealers Madness could also make an appearance.
The Who's Roger Daltrey has reportedly said the band has recorded a piece of music that would be "a fabulous ending to the Olympics." The classic rock band have long been linked with the Games, with rumours circulating months ago of uninformed organisers approaching the group asking about the possibility of them getting back together with drummer Keith Moon - who's been dead since 1978.
On the pop side of things Take That, Elton John and the Spice Girls are rumoured to be taking part, as is boyband of the moment One Direction.
Reclusive singer Kate Bush is also suspected to be making an appearance after a remix of her song "Running Up That Hill" was apparently posted on Amazon with a release date of this Sunday, only to be taken down a short time later.
The scale of the ceremony is expected to be smaller than Danny Boyle's epic opening show a couple of weeks ago.
The British newspaper the Daily Mail published photographs of what it said were the sets for the closing ceremony which included reduced-scale reconstructions of some of the city's most famous landmarks, including the London Eye, Clock Tower at Parliament, St Paul's Cathedral and Tower Bridge.
The cast will be made up of more than 4,000 local volunteers with 400 children involved and the ceremony will include the raising of three flags, those of Greece, host nation Britain and Brazil which holds the 2016 Olympics, and the extinguishing of the Olympic flame.
