Legendary bassist Geezer Butler (BLACK SABBATH, HEAVEN & HELL) has admitted to Canada's Exclaim! that he's unsure what his next professional move is going to be following the recent passing of HEAVEN & HELL singer Ronnie James Dio."We're all just on hold since Ronnie passed away," revealed Butler. "We did a tribute concert for his cancer fund a bit ago and that's about it. We're just wondering what to do next." He added, "It's really difficult because it's obviously never happened to us before. It's difficult to know what to do, especially at our age. We're not sure. Do we start all over again? We're just gonna see how it goes. That's the thing. He's a very close friend of of mine, as well as someone I work with. It's a big part of my life gone. [Are we] getting a singer in and that kind of thing? ... It'll sort itself out eventually, I suppose, [but] HEAVEN & HELL is finished. It could only ever be with Ronnie. I'd still like to carry on with Tony [Iommi, guitar] and Vinny [Appice, drums] doing something but it won't be as HEAVEN & HELL." Regarding the possibility of a reunion with Ozzy Osbourne and the prospect of new live shows by the original lineup of BLACK SABBATH, Butler said, "We're all talking again so that's a good sign — I hope. As far as the original band goes, there are so many places we never played that I'd love to visit. Japan for instance. We never ever played there or so many places in Eastern Europe or Asia that have opened up since the original band — or since the reunion of the original band. When we got the reunion thing back together, we really only played North America and Western Europe. That was it... Eventually I'd like to go to places we've never been there before. But it's easier said than done." Read more from Exclaim!
