“Somebody came to stab me one night on the ‘Vol. 4’ tour, which wasn’t very good. I’ve had some embarrassing moments onstage too – we’ve had a lot of things blow up onstage.
"One of them wasn’t that long ago with the original lineup. We were doing this show in Los Angeles and we were special guests, surprise guests I should say. It was 100-odd thousand people and a revolving stage. We were at the back waiting to come on – they weren’t going to announce us or anything. We were going to come round and start playing, which we did then… nothing.
“As the gear had turned round it had ripped all the leads out of the amplifiers and it blew everything. It was being filmed by television as well. So embarrassing. My guitar tech nearly had a fit – he didn’t know what the hell was going on either.
"I was saying: ‘What’s happening - what shall we do?!’ We walked off and had to borrow Zakk Wylde’s gear. We were supposed to have another one of these shows in New York, but said forget it – it really put me off after that.”
