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.

I finally came to the decision that I couldn't do it like that anymore. So I surrendered to that. I did (the Sabbath reunion tour) without anything - cigarettes, tobacco, dope, anything. And I had so much more fun without it.

There are no incurable ills.

When you get to 60, the word "retirement" comes in on every conversation.

Occasionally, I go off the rails. I once nearly killed somebody once - it wasn't funny. I am a lunatic. The pressure of work, the pressure - everyone has a stop valve, and I don't have one.

I have a genuine love affair with my audience. When I'm on stage they're not privileged to see me. It's a privilege for me to see them.

Randy [Rhoads] was laid to rest at a place called Mountain View Cemetery, where his grandparents were buried. I made a vow there and then to honour his death every year by sending flowers. Unlike most of my vows, I kept it. But I’ve never been back to his graveside. I’d like to go there again one day, before I finally join him on the other side.
