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

“The funny thing about getting married in America was that we needed to get a blood test before they’d give us a licence. I wouldn’t have been surprised if the bloke from the lab had called back and said, ‘Mr Osbourne, we appear to have found some blood in your alcohol.’”

“Officially, we didn’t have a band leader.Unofficially, we all knew it was Tony [Iommi].”

“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?”

“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.”

“As far as we were concerned, we were just a blues band that had decided to write some scary music.”

“‘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.’”
