Now, Butler claims Ward has been invited to perform at the band's final US show in Phoenix, AZ on September 16. "It's been mentioned to him," the bassist tells Radio.com. "But he doesn't want to do it. He wants to do the whole tour or nothing. We'd love him to come on at the very last gig and be part of the whole thing, but he didn't want to do that. And I understand: I wouldn't want to be asked to come out just for the last gig. It's a shame, but that's the way it is."

"If he's there, he's welcome," says Ozzy Osbourne. "But I don't really want to talk too much about Bill Ward! Because every time I do, he starts getting pissed off at me! Things are quiet between us right now, you know?"

"It's a shame that Bill won't be a part of it, but whatever happened, happened," adds Butler. "It's great that at least the three of us can end it on a high note and be friends together. I still get on with Bill, I saw him last year at some award show. We got on great, we had a laugh together. It's not personal, as Bill would say, it's business."

Ward denies the invitation and has stepped up to issue his side of the story. "I must respond once again to inaccurate statements made by Geezer," writes Ward on Facebook. "I never received an offer to play the final show of The End tour with Black Sabbath. When the tour was confirmed, my management reached out to the Black Sabbath management to inquire as to whether or not they would like to discuss my participation in the tour. We were told there was no interest. That is last conversation we had with them regarding the tour.
