Mick Fleetwood - 67 Years Old

The drummer has been in Fleetwood Mac from its start as a British blues band in the '60s through '70s superstardom as a trans-Atlantic pop group. The lanky Englishman has also done solo projects, penned an autobiography, played a record executive in Showtime's made-for-cable movie Mister Music in '99 and co-founded FleetwoodOwen, a company which conducts auctions of rock and roll memorabilia.
