I don't go see these bands these days even if I thought they were fantastic in their prime. This goes for the Clapton, Allman Brothers, Santana,The Pretenders,Pink Floyd, Jethro Tull, Zeppelin,etc.and yes even the Rolling Stones.
I would go see Jeff Beck if he was alive still as I never saw any decline with him. I'm sorry but at a certain point I think it becomes rather pathetic.
