We're only three days away from the closing of the 2012 London Olympics, at which point we will have to wait until 2016 for Olympic fever to kick off again, but the party that can be expected for the Closing Ceremonies is expected to be out of this world.

The two-and-a-half hour closing event, entitled "A Symphony of British Music," is rumored to showcase performances by a bevy of British stars, including Elton John, George Michael, Queen, Ray Davies, the Who, Muse, and the Spice Girls, reports Entertainment Weekly. Adele is reportedly set to sing "Someone Like You," and members of Pink Floyd will come together to perform their legendary "Wish You Were Here."

But that's not all. The London Symphony Orchestra is expected to perform, and Queen Elizabeth II is slated to … wait for it … make a speech!

David Arnold, the music director of the event, has played it close to the vest, not revealing an official roster of performances, but he did reveal that he "went through The Guinness Book of Hit Singles, from 1956 onwards, looking at the top 20 records for that year, and reducing that to 10 for each year. So you've gor more than 500 songs, all of which … were brilliant, any combination of which would make for an amazing show."

Tune in to see the 2012 Olympics closing ceremonies Sunday 7 p.m. EST on NBC.
