sadiej, that's an interesting way to take that comment.
I took that "20 years....it doesn't matter..." comment completely differently: like, he's had a career in music for 20 years where he was at the top of rock 'n roll for most of that time, but what he's doing now musically isn't going to make a difference because all that people want to hear is his hits from the old days and that's all people think about when they see him. I took it almost like an excuse, or a justification: "THIS is why I drink. I was at the top of rock 'n roll for 20 years but what I'm doing now isn't going to scratch the surface of any of that, I'm in a cover band with a bunch of nobodies, and I'm depressed about it, so I drink and lock myself on the tour bus."
I didn't even think about it the other way. I wonder which way he meant it.
