Annie Lennox, Spice Girls and more: Olympics Closing Ceremonies breakdown

annie-lennox-olympics.jpgFrom Annie Lennox to the Spice Girls and Adele, rumors about which British pop stars would be performing in the 2012 London Olympics Closing Ceremonies have been flying fast and furious.

The ceremony, called A Symphony of British Music, is livestreaming on NBCOlympics.com beginning at 4 p.m. ET, but London's Telegraph has posted an outline of the entire spectacle.

Here's a breakdown:

In a segment called "Rush Hour," the Spice Girls perform atop London black cabs in updated versions of their Sporty, Ginger, Scary, Posh and Baby outfits.

After the Kinks' Ray Davies sings "Waterloo Sunset," his "love song to London," Lennox performs in a "ghost ship with black sails."

Comedian Russell Brand is then expected to sing a punk tune, predicted to be the Sex Pistols' "Pretty Vacant," atop a multicolored bus.

Prepare to whistle, because Eric Idle follows with Monty Python's "Always Look on the Bright Side of Life."

The march of athletes will be followed by songs or performances from Adele, Pet Shop Boys, One Direction, Liam Gallagher, David Bowie, Brian May, Elton John, the Rolling Stones, the Clash and Kate Bush.

A performance by George Michael will be his first since he was critically ill last year.

Last week the "Faith" pop star tweeted, "Obviously a bit nervous not having played for nearly a year, but rehearsals sounding great so far!"

NBC will air the Closing Ceremonies on tape delay at 8 p.m. ET.
