Road manager for Frank Zappa during the 70s. The madcap behaviour & overtly sexual antics of Perellis provided Zappa with many ideas for his themes. McMacken included a Perellis incident in his illustration for the cover of Over-nite Sensation. Perellis is depicted as the two-headed character on the bed (somewhat pre-dating Zaphod Beeblebrox), ejecting the contents of a gas canister that bears his name.
