Conflict had existed between Iommi and Osbourne from the beginning. When responding to a 1969 flyer reading "Ozzy Zig Needs Gig- has own PA" posted in a record store, Iommi and Ward arrived at the listed address to speak with "Ozzy Zig." When Iommi saw Osbourne emerge from another room of the house, he left upon discovering it was the same "pest" he knew from growing up, as he knew of and disliked Osbourne from back in their school days. Iommi had reportedly "punched out" Osbourne numerous times over the years when the singer's drunken antics had become too much to take. Iommi recalls one incident in the early 1970s in which Osbourne and Butler were fighting in a hotel room. Iommi pulled Osbourne off Butler in an attempt to break up the drunken fight, and the vocalist proceeded to turn around and take a wild swing at him. Iommi responded by knocking Osbourne unconscious with one punch to the jaw.
