“I used to get upset by people not understanding me, but I’ve made a career out of it now.”

“A lot of people came up to me that night and asked, ‘How come you and Sharon have stayed together all this time?’ My answer was the same then as it is now: I’ve never stopped telling my wife that I love her; I’ve never stopped taking her out for dinner; I’ve never stopped surprising her with little gifts.”

“The thing is, I’ve never believed in feuds. Don’t get me wrong: I’ve been angry with people. Very angry – with people like Patrick Meehan, or that lawyer who tried to bill me for a drink, or Bob Daisley. But I don’t hate them. And I don’t wish them any harm. I reckon hating someone is just a total f**king waste of time and effort. What do you get out of it in the end? Nothing. I’m not trying to come over like the Archangel Gabriel here. I just think that if you’re pissed off with someone, call them an arsehole, get it out of your system, and move on. It’s not like we’re on this earth very long.”

“I hardly ever went to the AA [alcoholics anonymous] meetings. I’ve just never felt comfortable in those places. It’s my worst zone. I’ll get up and sing my heart out in front of two hundred thousand people at a rock festival, but when I’ve got to talk about the way I feel to people I’ve never met before, I can’t do it. There’s nothing to hide behind.”

“Meanwhile, we’d been kicked out of school at fifteen and had worked in factories and slaughtered animals for a living, but then we’d made something of ourselves, even though the whole system was against us. So how upset could we be when clever people said we were no good?”

“Even now, I have a lot of trouble understanding why Sharon stayed – or why she married me in the first place, come to think of it. I mean, she was actually afraid of me half the time. And the truth was I was afraid of me, too. Afraid of what I’d do to myself or, even worse, to someone else.”

“Today you hear people saying that we invented heavy metal with the song ‘Black Sabbath’. But I’ve always had a bee up my arse about the term ‘heavy metal’. To me, it doesn’t say anything musically, especially now that you’ve got seventies heavy metal, eighties heavy metal, nineties heavy metal and new - millennium heavy metal – which are all completely different, even though people talk about them like they’re all the same.”
