“Like my father always said to me, if you ever pull a weapon on somebody – no matter what it is – you’ve got to be fully prepared to use it, because if you’re not, the other guy will see the doubt in your eyes, and he’ll take it off you and use it on you instead. Then you’re really in trouble.”

“If you’re determined to commit suicide, you’ll blow your brains out or you’ll jump off a tall building. You’ll do something that you can’t take back, in other words. When you ‘try to kill yourself’ by taking too many pills – like I did – you know you’re probably gonna get found by someone. So all you’re doing is sending a message.”

“My father always said I would do something big one day.‘I’ve got a feeling about you, John Osbourne,’ he’d tell me, after he’d had a few beers.‘You’re either going to do something very special, or you’re going to go to prison.’And he was right, my old man.I was in prison before my eighteenth birthday.”

“You never really know what’s going on inside Tony Iommi’s head. He’s the total opposite of me, in other words: no one’s ever in any doubt about what’s going on in the pile of old jelly inside my thick skull.”

“‘Dad,’ said Jack one day. ‘When you’re on the telly, d’you think people are laughing with you or at you?’The question had obviously been bothering him for a while.‘Y’know what,’ I said to him, ‘as long as they’re laughing, I don’t care.’‘But why, Dad? Why would you want to be a clown?’‘Because I’ve always been able to laugh at myself, Jack. Humour has kept me alive over all these years.’And it’s true, y’know.”

“Another memorable performance of ‘Black Sabbath’ was in a town hall near Manchester. The manager was there to greet us in a suit and tie when we climbed out of the van. You should have seen the look on his face when he saw us.‘Is that what you’re going to wear on stage?’ he asked me, staring at my bare feet and pyjama top.‘Oh no,’ I said, in this fake-shocked voice. ‘I always perform in gold spandex. Have you ever seen an Elvis gig? Well, I look a bit like him – but of course my tits are much smaller.’”

“It’s funny, you learn a lot about people when you’re on the road like that. Every morning, for example, Bill would have a cup of coffee, a glass of orange juice, a glass of milk, and a beer. Always in the same order. I asked him why he did it once.‘Well,’ he said, ‘the coffee’s to wake me up, the orange juice is to give me some vitamins to stop me getting sick, the milk’s to coat my stomach for the rest of the day, and the beer’s to put me back to sleep again.’”
