“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.”
