Bill Ward

Drummer Bill Ward tried to listen to '13,' the album Black Sabbath recorded without him following a contract dispute, but he had to stop after only a few difficult moments.

For original Black Sabbath drummer Bill Ward, there's a simple explanation as to why he didn't record or tour with his bandmates. "I was offered a contract, and I couldn't sign it," he said in a recent interview. He refutes suggestions that he wasn't physically up to the task.
