The competitions will end Sunday, but then expect fetes that organizers say will be of Olympic proportions.
Consider music director David Arnold's prediction: it will be "the greatest after-party in the world."
"If the opening ceremony was the wedding, then we're the wedding reception," Arnold told the Daily Telegraph — with everyone from the Pet Shop Boys to Annie Lennox and Fatboy Slim on hand to get people dancing.
Organizers have tried to keep the ceremony under wraps, but details have leaked out in the British media. Some of the performers have let the cat out of the bag themselves.
The Who, George Michael, Muse and Ed Sheeran have all said they will take part in a show that will include performances of 30 British hit singles from the past five decades.
Of course, there will also be ceremonial elements, including an athletes' march, the raising of the flags of Greece — birthplace of the Olympics — current host Britain and 2016 Games host Brazil, and the extinguishing of the Olympic cauldron, marking the handover to Rio.
But the main event will be a mashup of music, theater, circus and hit parade.
