A Black Sabbath reunion is far from a sure thing, but the four original band members (vocalist Ozzy Osbourne, guitarist Tony Iommi, bassist Geezer Butler and drummer Bill Ward) have made it clear that they’re taking baby steps to make it happen.

The four original members of Black Sabbath recently got together in a rehearsal room to jam for the first time in a handful of years.

“[We] played some of the old stuff and to be together again was great,” guitarist Tony Iommi said in an interview with the UK magazine Terrorizer. “We’re all on good terms and we’re at a stage where we can play together again. It would be good if we could and I suppose it’s the closest it’s been to be able to do that. It could happen.”

Iommi’s comments support Osbourne’s comments to Ultimate Classic Rock last week: “I’m not saying too much about it because we’re just at the gates, but it’s a good possibility.”

In a new interview with U.K. digital radio station Planet Rock, Iommi reiterated that a reunion is a possibility, but while he has his fingers crossed he’s not dropping any other plans quite yet.

“We haven’t announced anything yet, because nothing’s definite,” he restated. “We’re taking it steady, because these things have a tendency to backfire. ‘Oh, you said you were getting back together, but you haven’t.’ So I don’t know. We’ll have to see. It would be nice to think we could, and I think we would all like to do it, but it’s a bit more involved than that.”

The Black Sabbath 2011 jam marked the first time the band have played together since 2005. In 2006, guitarist Iommi and Butler got back together with Ronnie James Dio and eventually formed Heaven & Hell, which recorded one album, 2009’s ‘The Devil You Know’ and toured extensively before Dio was diagnosed with stomach cancer in November 2009; he died just six months later from the disease.

Initial reports that the original Black Sabbath would re-form were sparked in August when Jack and Kelly Osbourne stated that their dad missed the Hollywood premiere of the documentary ‘God Bless Ozzy Osbourne’ because he was “doing something that is very, very exciting.”

One thing that’s definite regarding Black Sabbath: Iommi’s memoir ‘Iron Man: My Journey Through Heaven and Hell with Black Sabbath’ comes out Nov. 1. Iommi will sign copies of his book on a book tour that starts at Bookends in New Jersey on Nov. 1, continues at Book Revue in Huntington, N.Y. on Nov. 2 and ends Nov. 3 at Barnes & Noble in Tribeca, New York.
