I don't know.. to paraphrase his own words he didn't burn his candle at both ends he took a flamethrower to it..!! :flame
the prospect of him having something like the big C scares the shit out of me (he's really one of my all-time musical heroes) it's not just that he's aged badly, he's not old after all, or that the partying's finally caught up with him.. but frankly he looks seriously unwell, gaunt in the face
I also wondered about his hearing.. not being on point and improvising lyrics has always been his thing live on stage but he's totally out of kilter with everything and every line seems like a real effort for him now..
