Bohemian Rhapsody

Bohemian Rhapsody one of the best known rock songs of all time. Many attempt to cover it, many parody it, but there is only one group who can perform it to it's ultimate style. That of course is Queen, and they have to have Freddy up front.
But just for fun here are some other versions, in addition to a wonderful live one from Queen.

Queen - Live at Wembley Stadium in 1986

Lee Evans - sound by Queen

Rick Miller - and 25 most annoying voices

Mnozil Brass

Edgar Cruz - classical guitar
