If you give a good performance, something that gets some feeling across to people, that’s such a rare gift. It’s underestimated at this point in history, when the music biz is inevitably turning into a kind of politics.

I wanted to learn a little bit about acting, not because I thought I'd find a star vehicle and set the world on fire, but I thought the discipline of it would be good for me. I met a good coach, and I joined her class - with a lot of hungry young actors who really didn't acre if I was a rock 'n' roll singer or not. I started to learn to get a focus, without having to jump up and down every few seconds.

I don't get my bliss by listening over and over to people in the street thinking, "Boy, is it that good?" Even though every time I hear it that's what I think. But I get it in human situations. There is this little voice that is going, "The reason you're able to enjoy your life now is that you made it in rock'n'roll and people are giving you free visas all over the place. Dude, you are being spoiled".

In 1965, when great young white artists in the English-speaking world were successfully re-channeling hillbilly and black music - you know Bob Dylan, Ray Davies, Pete Townsend, Keith Richards - they didn't get any money at first. They were all broke.

The problem being: for years I was struggling - first to prove that I had any talent, then to create some skills and finally to fulfil it reasonably. But then once I got there it was, "OK. I did that, but I want to be happy." And that's a whole different deal. It's kind of like a dance. Being active seems to help. I'm 70, so sometimes a little voice is going, "Just take it easy".

Musical types tend to combine the burden of the author with the burden of the actor.

When the 'godfather of punk' thing started floatin' around, it was, I was really, really embarrassed. I thought I should have a great, big rig and a cape and everything, and it was very embarrassing. And then after a while, you learn that if people call you anything, this is a great gift.
