When Black Sabbath announced they were reuniting, many doubted they would really manage to pull it off.

Things started badly as guitarist Tony Iommi was diagnosed with cancer.  Then drummer Bill Ward refused to continue saying he wasn't making enough money.

Ozzy, Tony and bassist Geezer Butler didn't give up though, recording the cd with Rage Against The Machine Drummer Brad Wilk and touring with Ozzy drummer Tommy Clufetos.

Despite some public bitterness, Ozzy wants Bill back for a final record and tour before they officially retire Black Sabbath. FOREVER. He told Esquire magazine:

What I'm really happy about is, if this is Black Sabbath's last hurrah, then we'll have ended it on an up note rather than when I left in 1979 and everybody was f***ed up on one thing or another and I was marked out as being the worst, you know. It ended on a bad note, so...”

“The only thing sad about it is I hope Bill Ward can get his stuff together to do this because... one of the biggest things I'm proud of in my life was that Black Sabbath wasn't a band that was created by some business mogul in London or New York. That we were four guys who had a great idea and it worked from record one."

"13" was Sabbath's first number 1 record in 45 years.

We'll see how this one does ... if it happens at all.
