It was always fun in the early days of Black Sabbath, when I stayed away from heavy drugs. Then someone gave me cocaine and I went, "Hallelujah!" I thought I'd found the meaning of life!

A Christian man is a man who is within himself, who puts out good vibes.

I don't know if I'm a medium for some outside source. Whatever it is, frankly, I hope it's not what I think … Satan.

At 18, if someone had said to me, "I think you should go to rehab and get cleaned up," I would have thought, "You're fucking mad."

I love my wife. We've had a few slings and arrows across the room, but I'm not prepared to give in, you know? People say she saved my life, but at the same time, I saved her life, as well, I think. She's a great mother, she's a great wife, she's a great worker, she's a great manager. She's just great.

There was a cinema called The Orient outside the community centre where we rehearsed in Six Ways, and whenever it showed a horror film the queue would go all the way down the street and around the corner. 'Isn't it strange how people will pay money to frighten themselves?' I remember Tony [Iommi] saying one day. 'Maybe we should stop doing blues and write scary music instead.'

People want it to be red, like blood. It's kind of funny. When I used to throw meat into the audience, I'd get letters from kids' mothers saying, "What's the best way to get blood stains out of my son's shirt?"
