Olympics: Closing Ceremony to include The Who and Spice Girls

London - The 2012 Olympics will come to an end Sunday night, August 12, with a celebration of not only the athletes, but also 50 years of British pop music.

Artistic director Kim Gavin said the closing ceremony will be "the best after-show party of all time," BBC News reports. The ceremony, which will feature acts such as The Who, Spice Girls, and Muse will be a "mashed-up symphony of British hits," Gavin said. George Michael, Annie Lennox, Fatboy Slim, and Ray Davies (former leader of the Kinks) are also scheduled to perform, the LA Times reports. The Pet Shop Boys are also set to perform, The AP reports. According to BBC News, British rapper Tinie Tempah will reportedly be performing as well, but this has not been entirely confirmed. The acts have not been confirmed by the organizers, but some of the performers have been leaked by the British media and by the artists themselves. Last month, a source confirmed to US Weekly that the Spice Girls would indeed be there. There are pictures of the group rehearsing on PopSugar. According to The AP, Kim Gavin is no stranger to directing major concert events. In 2007, he directed London's Princess Diana memorial concert. Olympics closing ceremony music director David Arnold told The Daily Telegraph, "If the opening ceremony was the wedding, then we're the wedding reception." According to The AP, the ceremony will also feature eight minutes of song and dance from the 2016 Olympics host country, Brazil.
