For years I've had neurological problems. I used to shake a lot and I was on medication - I paid about $700,000 for one year of pills. I was taking 40-odd different ones a day.

In those days, if you wanted a new car or a holiday, you'd phone up the office and they'd send you some cash. You never had a bank account. I don't know anyone from the music business in the Seventies that it didn't happen to.

And I never missed one concert. In 89 shows, I think I did one a bit suspect show. In the old days, I'd pull gigs left, right and center because I was too f - - up.

I feel joy when I do a great show.

There's no present, there's no future, I don't even know about the past.

I'm not trying to twist people's heads around. I'm not trying to say, "Believe in me."

I don’t know whose brilliant idea that was, but it wasn’t mine, that’s for sure.
