Tony Iommi, in a new interview, reveals that he talks to Ozzy Osbourne often and says that a Black Sabbath reunion will happen again -- provided that all the band members are still alive and kicking.

The Sabbath guitarist and songwriter talked to the publication The Quietus while attending a new exhibit on the history of heavy metal at the Birmingham Museum and Art Gallery in England.

"We’ve been doing all different stuff," said Iommi. "I just talked to Ozzy this morning – we talk about three times a week. He’s doing his tour and I’ve been doing stuff with Ian Gillan, I’ve done a few tracks with him, and I’ve been doing me book. So, when the time is right. If we’re still alive."

In referencing Deep Purple's Ian Gillan, Iommi is speaking of their work together in the group WhoCares, which also features contributions from ex-Metallica bassist Jason Newsted and Iron Maiden drummer Nicko McBrain, among others. The outfit recently released a two-song charity CD single in Europe containing the songs 'Out of My Mind' and 'Holy Water.'
