Greatest rock band of all time

Gotta go with Lynyrd Skynyrd circa mid-seventies. Three guitarists, Ronnie Van Zandt, and a whole slough of great songs! Tough to beat. The Beatles were good, though. Pink Floyd, too. But Skynyrd really did it up fine. Oh HEY, mustn't forget about Def Leppard, either. Late eighties version.
