I'm into rock'n'roll because rock'n'roll, to me, means freedom.

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.

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."

It was such an amazing time for music in the Sixties. When popular music hit me, it was like magic was in the air.

But the thing with us was, we didn’t really need anyone to make us world famous – we were already halfway there.

You've got to believe in yourself, or no one will believe in you. Imagination is like a bird on the wing, flying free for you to use.
