“‘Paranoid’ went straight to number four in the British singles chart and got us on Top of the Pops – alongside Cliff Richard, of all people. The only problem was the album cover, which had been done before the name change and now didn’t make any sense at all. What did four pink blokes holding shields and waving swords have to do with paranoia? They were pink because that was supposed to be the colour of the war pigs. But without ‘War Pigs’ written on the front, they just looked like gay fencers.‘They’re not gay fencers, Ozzy,’ Bill told me. ‘They’re paranoid gay fencers.’”

“We set up our gear for the tune-up and Tony [Iommi] launched into the opening riff of ‘Black Sabbath’ – doh, doh, doooohnnnn – but before I’d got through the first line of lyrics the manager had run on to the stage, red in the face, and was shouting, ‘STOP, STOP, STOP! Are you f**king serious? This isn’t Top-Forty pop covers! Who are you people?’‘Earth,’ said Tony, shrugging. ‘You booked us, remember?’‘I didn’t book this. I thought you were going to play “Mellow Yellow” and “California Dream-in’”.’‘Who – us?’ laughed Tony.‘That’s what your manager told me!’‘Jim Simpson told you that?’‘Who the hell’s Jim Simpson?’‘Ah,’ said Tony, finally working out what had happened. He turned to us and said, ‘Lads, I think we might not be the only band called Earth.’He was right: there was another Earth on the C-list gig circuit. But they didn’t play satanic music. They played pop and Motown covers.”

“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.”

“That night, at God knows what hour, Bill phoned me up and shouted, ‘Ozzy, I think myhouse is haunted!’‘Sell tickets then,’ I told him, and put the phone down.”

“‘Ozzy, why do you drink so much? What’s the point?’The right answer to that question was: because I’m an alcoholic; because I have an addictive personality; because whatever I do, I do it addictively. But I didn’t know any of that back then.”

“All those Jesus freaks ever had to do was listen to my records, and it would have been obvious. But they just wanted to use me for publicity. And I suppose I didn’t care that much, ’cos every time they attacked me, I got my ugly mug on the telly and sold another hundred thousand records. I should probably have sent them a Christmas card.”

“I remember one time, back in the day, I was at his [Bill Ward] house and he said, ‘Oh, ’ello Ozzy. You’ll never guess what? I’ve just come out of a coma.’‘What d’you mean, a coma? That’s one stage removed from being dead. You know that, don’t you, Bill?’‘All I know is I went to bed on Friday, and now it’s Tuesday, and I only just woke up. That’s a coma, isn’t it?’‘No, that’s taking too many drugs and drinking too much cider and sleeping for three days in a row, you d**k.’”
