The much fabled jam session that took place between two of rock 'n' roll's super-heavy weights, Black Sabbath & Led Zeppelin, did happen, according to Bill Ward.
However fans who have been waiting years anticipating the release of this 'ultimate jam' session should not hold their breath, as the Brummie drummer has revealed that the recordings don't even exist.
But the jam did happen, just the once and the Sabbath legend says watching Led Zep's, John Bonham play with two bass drums was unforgettable.
Speaking with Back Page Magazine: "Zeppelin and Sabbath were in the studio at one time, and it only happened on one occasion. I don’t remember what album we were working on, but we were in sessions and it all started when Bonzo came into the studio and sat down at my kit.
"He starts playing Supernaut, one of our songs that he really liked. His bass drum work was incredible. I played two bass drums and they only let him play one in Zeppelin. Supernaut sounded like something from the hardcore bands of today, and Bonzo was doing that easily.
"He was having a good time, playing it with a whole different feel, all the while yelling ‘Supernaut!’ the whole time. It was crazy."
Ward goes on to recall: Jimmy Page wasn’t there, but I wish he had been. And all the time Bonzo was kicking the crap out of my drum kit.
"There was a moment during that jam where we all kind of got this crazy notion and said, ‘Let’s put something down on tape.’ But nothing transpired and no tape rolled. Nothing was recorded – we were just pissing about.
"I believe at one point Geezer Butler and Robert did a bit of writing together – but that was their own personal thing, between them. The Black Zeppelin recordings didn’t ever exist."
