I have a night off on Halloween. It's Halloween for me every night. Let everybody else be Ozzy for the night. People go out dressed as me.

Nobody ever told me, I found out for myself, you got to believe in foolish miracles.

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.'

Rock music is not meant to be perfect.

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 grew up having to piss in a bucket ’cos there was no indoor shitter, and now I have these computerised Japanese super-loo things that have heated seats and wash and blow-dry your arse at the touch of a button. Give it a couple of years and I’ll have a bog with a robot arm that pulls out my turds, so I don’t have to strain.

Did you know that the percentage of young people in the crucial 'youthquake' age bracket of 15 to 24 was higher in 1973 than in 1967 ? Therefore it was glam rock that ended the war in Vietnam.
