Music will be the highlight of the event and the bill includes performers ranging from the Spice Girls and George Michael to Muse and the London Symphony Orchestra.
"Everyone is calling it the biggest closing ceremony they have ever seen," director Stephen Daldry said. "I am really hoping that people will gather at the live sites and in their homes and pubs and have the time of their life."
Closed rehearsals have been under way at a Ford auto plant in east London where celebrity-watching reporters have spotted the various stars coming and going. Rockers Annie Lennox and Brian May have been seen as well as Kate Bush and the Pet Shop Boys, The Daily Telegraph said Saturday.
Rumors abound that blue-chip stars such as Adele, the Who and Elton John will also be performing.
"It's a proper show," said Daldry, who directed "Billy Elliot." "It's got all the bizarre, surreal, funny, camp and moving elements you could want from a really good piece of Sunday night entertainment."
