Sparmac (Sparmac Productions) was an Australian independent record production company and recording label of the early 1970s, best known for its association with the successful Australian rock band Daddy Cool. The company was established ca. 1969 by radio DJ (and former Kommotion host) Ken Sparkes, and John McDonald, who was then the owner of popular Melbourne record store The Disc Shop, in Bourke Street, Melbourne. The company name was taken from the combination of their surnames. In 1970 Sparkes subsequently sold his share to the label's first recording artist, Robie Porter. Porter, a former teenage guitar prodigy, had enjoyed a very successful recording career under the stage name "Rob EG" in the early Sixties.
