"I used to dream a lot. I joined a band because I loved The Beatles and it was a good way of being with the lads. We'd be on the road with two bob between us. Someone would say, 'What shall we do with it? Four lots of chips, or 10 No 6?' And we'd always vote for the fags." The band, of course, was an early version of Black Sabbath, one of the most influential rock'n'roll outfits of all time. Since its inception, Black Sabbath has sold more than 70 million albums worldwide. Yet in those days, says Ozzy, they'd pile into the back of a van holding a piece of paper that said "De Montford Hall, Leicester: you're on stage at 8.30pm", and have to ask the way when they got there. Ozzy recalls this innocent era with fondness. "I'm just like my dad. He never liked change either." One thing that doesn't change, he claims, is an addictive personality. Today's preferred method of self-abuse is television. "I'm a TV addict, if anything. I'm drawn to the destruction of mankind, all that stuff on the Discovery Channel - I call it the Hitler Channel - the wars, bombs, all that dark stuff. I must have watched The World at War 5,000 times. I suppose I'm one of those people who likes to see a car crash. I've always been like that."
