David Donato
From Wikipedia
David "Donut" Donato, male model, known for his involvement in Black Sabbath as singer, after Ian Gillan's leaving. He stayed for a very little period in 1984, since he was fired up by the band bacause of an arrogant interview Donato released to a magazine. Bill Ward gave him his nickname because Donato used to eat donuts during the rehearsal. The Butler/Iommi/Donato/Ward line-up didn't release anything.
