The members of Black Sabbath say that there's still a chance for founding drummer Bill Ward to return to the band. Ward has so far sat out the legendary metal act's reunion -- not participating in the recording of a new album or live shows -- due to his dissatisfaction with the contract he was offered. But singer Ozzy Osbourne told NME.com. "The door is open. As far as I know his requests were very unreasonable. Nothing would have been better (than) if he would have been (willing to play with us). I don't know. I don't deal with the business."
