I am 54 years old. I remember when all these bands came on the scene. If anyone would've said in the late '60's that Mick Jagger, Keith Richard, Pete Townshend, Roger Daltry, Robert Plant and Jimmy Page among others would be performing into their 60's and people still wanted to see them, the odds would've been like 4 million to one. Everyone thought most of these guys would be in a drug-induced vegetable state well before they reached 30. Even some of the women..like the Wilson sisters, Ann and Nancy, are still rocking in their 60's...I think it's f-----g great!
