McNabb worked on soundtracks for film and television (Once Were Warriors, Broken English, Greenstone), enjoyed sonic experiments in the recording studio, won awards for the America's Cup anthem Sailing Away and the Red Nose Day song, arranged orchestras and choirs for outdoor concerts and was a talented painter.
Recently, he said of his different careers in advertising and making his own music: "I've come to believe the real art is selling, sell yourself or sell your product, whatever it is. "Otherwise you just do it for fun, and I do [my music] for fun. I get paid sometimes, but I've got paid enough [from commercial work] to be able to do it and have fun."
Always pushing the boundaries in his often unscripted music, McNabb had a favourite saying on the wall of his home studio: "The new man must have the courage to be new."
Murray McNabb died after a year-long battle with cancer but even in his final weeks was still recording and performing. He is survived by his partner Koula Coulouris and three adult children.
