Dave, who was flautist and saxophonist with Sydney band Flake, played with Iva Davies on a recording of film music written by Steve Gard. This was some time before Icehouse (initially Flowers) was formed, and it seems to have been Iva Davies' first recording.
Dave tells the story at his Burning Mountain Studio blog:
In 1972 Iva was a student at the Sydney Conservatorium of Music. (Steve and myself also went there at other times). Steve was involved with the New Theatre at the time, where he met Chris Noonan (these days a Hollywood director [Babe, etc]) and Chris asked Steve to score music for a movie called Garbo he was making. Steve wrote the theme music and we recorded it at ATA studios in Glebe. Iva played oboe and tuba, Steve played guitar and piano and I played flute.
