In the early days, you would get skinheads, the Eagles and Black Sabbath playing the same show.

The rest of the guys in Sabbath became boring old farts, and there I was, this crazy guy, still into wrecking hotel rooms and having parties.

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.'

Life's not all about money.

My heart stopped twice. They had to stab me to drain the blood from my lungs because I was drowning in my own blood.

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.

God is within you. God is a nice feeling. He's the flowers and smells and the nice things in life.
