Best musical act at the Olympics Closing Ceremony?

The Spice Girls perform during the Closing Ceremony at the 2012 Summer Olympics, Sunday, Aug. 12, 2012, in London.

Did the Spice Girls spice up your life last night? The "Girls" (now pushing 40 with plenty of babies between them) reunited Sunday night for the Olympics Closing Ceremony -- and even London Mayor Boris Johnson couldn't help but dance along to "Wannabe" and "Spice Up Your Life."

However, we were a little worried that Victoria Beckham was going to fall off that car she was teetering on!

Overall, the Closing Ceremony felt like one big rock concert. George Michael has had his share of personal problems, but he had plenty of fan support as he took the stage to sing his 1990 hit, "Freedom." We'd never heard of British pop star Jessie J, but apparently she's big enough to be chosen to sing "We Will Rock You" with Queen’s Brian May. But fans were furious when NBC delayed The Who's performance to show a preview of its new comedy "Animal Practice."
