"Ronnie had started to take over a little bit too much and was becoming a bit of a Hitler," Iommi explained to Steve Gett of "Guitar for the Practicing Musician". "We were working on the "Live Evil" record in Los Angeles, and in fact we nicknamed him 'Little Hitler.'" In his 2011 memoir, Iommi was considerably less harsh in his summation of Dio's behaviour, stating "By then Ronnie did come over a little more...I suppose, bossy. The way he conducted himself, the way he talked, it might have given that impression to the outside world, but he usually didn't mean anything by it. Ronnie was just very outspoken." Iommi also contends that he and bassist Geezer Butler were concerned about Dio already rehearsing with other musicians for a proposed solo album offered to him by Warner Brothers Records.
