Artistic director Kim Gavin has promised that Sunday’s Closing Ceremony for the London Olympics will be “the best after-show party that’s ever been.”

British rock stars expected to take the stage include headliners The Who, the surviving members of Queen and the Spice Girls.

Also: George Michael, Muse, Fatboy Slim and the One Direction.

The show will include performances of 30 British hit singles from the past five decades — whittled by Gavin from a list of 1,000 songs.

Gavin said the show would open with a tribute to the “cacophony” of London life, with a soundtrack ranging from late Edward Elgar, composer of the “Pomp and Circumstance” march, to The Kinks’ “Waterloo Sunset.” Frontman Ray Davies is expected to perform the 1960s song, a love letter to London.

In a switch from opening night and what appeared to be a concession to its vocal critics, NBC decided to stream the ceremony live online, in addition to broadcasting it during prime time.
