Born in Toronto, Patrick began playing piano for church dances in 1960 at age 12. Early influences were Fats Domino, Henry Mancini, Leonard Bernstein and JS Bach. He played and sang in a number of Toronto rock bands, including the Omegas, The Diplomats, and RCA recording artists Simon Caine. His performances led to session work with many well known Canadian musicians including Bruce Cockburn, Murray McLaughlan, Raffi, Marc Jordan, Shirley Eikhard, Ben Mink, Daniel Lanois, Ken Whiteley, David Essig, Fraser and Debolt and Mendelson Joe.
His work with singer Len Udow took him to Winnipeg one Summer around 1970, where he met Richard Condie and wrote the music for Richard's first animation, Oh Sure. So began a friendship which continues today; Patrick has scored all of Richard's animations including the Academy Award nominated classics The Big Snit and La Salla and most recently, Etudes and Impromptus.
