Jack D. Zastre was part of the Winnipeg new wave comix group Free Kluck, together with Roldo, Basil Hatte, Frank McTruck, Bobby Stahr and Dudley 'The Mushroom' Clearsky. He created among others a 'Star Wars' parody called 'Bar Wars' in the early 1980s. 'Bar Wars' ran for a couple of issues, and appeared in other self-published titles like 'Polar Funnies', 'Street Music' and 'Holey Script'.
Zastre's work has also appeared in 'The Nebula World of Elzon', 'Drunk Comix' and '40 Degrees Below Funnies'. Zastre and other members of Free Kluck later went on to form the bands Buffalohunter and the Mayhem Blues Band.
