Queen Elizabeth II Diamond Jubilee Concert

Grace Jones

In contrast to the less attention-grabbing outfit of Her Majesty, Grace Jones celebrated the Queen in a red-and-black get up Lady Gaga would probably love. Despite the shortness of her dress, the music diva worked up a sweat in her colorful headgear.  But she managed to entertain the crowd - and doing so while hoola-hooping throughout her song. 

Gary Barlow and Cheryl Cole

Cheryl Cole and Take That star Gary Barlow, one of the organizers of the jubilee concert, brought the crowd another duet as they combined their vocal skills for "Need You Now." Barlow is currently a judge on the U.K. version of The X Factor, a role that Cole previously also held.

Annie Lennox

Annie Lennox of Eurythmics fame brought her usual spunk and angel wings to the stage for the jubilee concert. Her band also wore wings as they performed, apprpriately, "There Must Be an Angel." Lennox ended the song by swinging the microphone to prepare the crowd for the next performer. 

Kylie Minogue

Australia's Kylie Minogue showed up in an eye-catching outfit and with a medley of hits. Among the songs she performed were "Spinning Around" and "Can't Get You Out Of My Head." Flanked by male and female dancers, Minogue also encouraged the crowd to "Step Back in Time."

Elton John

It wouldn't have been a big outing of British music star power without Sir Elton John. Dressed in a typicallt subtle (or not) pink glitter suit, he had the crowd - including Prince William and wife Kate Middleton - singing and clapping along to such hits as "I'm Still Standing" and "Crocodile Rock."
