Greg Macainsh and Imants "Freddie" Strauks both attended Norwood High School in the Melbourne suburb of Ringwood and formed Spare Parts in 1966 with Macainsh on bass guitar and Strauks on lead vocals. Spare Parts was followed by Sound Pump in 1968, Macainsh formed Reuben Tice in Eltham, with Tony Williams on vocals. By 1970 Macainsh was back with Strauks, now on drums, first in Claptrap and by 1971 in Frame which had Graeme "Shirley" Strachan as lead vocalist. Frame also included Pat O'Brien on guitar and Cynthio Ooms on guitar. Strachan had befriended Strauks earlier—he sang with Strauks on the way to parties—and was asked to join Claptrap which was renamed as Frame. Strachan stayed in Frame for about 18 months but left for a career in carpentry and a hobby of surfing in Phillip Island.
