Tony Iommi said early Black Sabbath rehearsals with Ozzy Osbourne went poorly, and they needed to lose members for Ozzy to find his voice.
Iommi told Backstaged, “We went to the music shops, as you do, and look up, on the board, and see if there’s any singers there. And we saw this one advert saying, ‘Ozzy Zig requires gig.’
“And I said to Bill [Ward, drums], ‘I know an Ozzy, he can’t be the same one because he didn’t sing as far as I know.’
“I never knew that he’d done anything, so sure enough, we went around his house, this address we had, and his mom answered the door, and she shouted for him, and he came.
“I knew him from school, but I didn’t have any idea at all that he could sing. We talked to him for a bit, and then we left. And a couple of days later, Ozzy came around to my house, I didn’t live that far from him.
“Basically, we teamed up, and that’s how it sort of started. It was a bit of an odd combination at first because nobody knew what everybody else could do.
“So we just started rehearsing, and it was very disorganized at first because Bill and myself were used to being in this other band, and we’d all gel, we had music that we played quite a lot, but when we got together with Ozzy and Geezer [Butler, bass], it was just strange.
“We had to start again and find out how Ozzy could sing and find out if Geezer could play bass – because he wasn’t a bass player when we first had him, he was a guitar player.
“So, he switched to bass. I think on our first rehearsal, Geezer was playing bass on his Telecaster, just playing the bass notes. Eventually, he got a bass and we went on from there.
“It didn’t seem to be going anywhere at first. It became a six-piece band where we had a sax player and another guitar player, slide guitar player, and it was a horrendous rail, to be honest.
“We sort of wondered what we were doing really, and then we decided we didn’t need a sax player and a slide player.
“So anyway, we felt comfortable about removing them. We’d say, ‘We’re gonna break up, we’re not gonna carry on.’
“And so that’s what we did, and we broke up for a week, and then we got back together again, just the four of us.”
He said the four piece worked better, “You could really hone in on it. It was just a playground. To be honest, when we had six of us, everybody was trying to do a solo at the same time.
“It was just horrendous, it just didn’t work all together, everybody tried to get bloody solos in.” Ultimate-Guitar transcribed his remarks.
