In 1979, Black Sabbath returned to the studio, but tension and conflict arose between band members. Osbourne recalls being asked to record his vocals over and over, and tracks were manipulated endlessly by Iommi. The relationship between Osbourne and Iommi became contentious. On 27 April 1979, at Iommi's insistence but with the support of Butler and Ward, Osbourne was ejected from Black Sabbath. The reasons provided to him were that he was unreliable and had excessive substance abuse issues compared to the other members. Osbourne claims his drug use and alcohol consumption at that time was neither better nor worse than that of the other members.
