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?"

I'm not a musician - I'm a ham.

I think if a man can create something like an atom bomb, he can surely create something with his own mind.

I hyperventilate opening a box of chocolates. I'm the most nervous guy in the world, a frightened little man on red alert from when I wake until I go to sleep. I was born with fear.

The introduction of heartache began as a child.

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.'

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.
