that his arm had gone numb. Iommi and Butler then left for a short time, not knowing the severity of Ward's condition. Outside, they saw an ambulance pass but weren't aware what was happening. Upon returning to the rehearsal space a short time later, a frantic Osbourne informed them "Bill has had a heart attack! Bill has had a heart attack!" As was the case in 1980, he was replaced at short notice by Vinny Appice, although this time it was always intended to be a temporary absence for Ward, health permitting. In 2000, Ward participated in a partial Black Sabbath reunion of sorts, joining Iommi and Osbourne to record the track "Who's Fooling Who" for Iommi's first solo album.
