In 1973 EMI producer Alan Galbraith amassed a supergroup of Kiwi musicians to provide session music for the label’s artists, including singer Mark Williams. The band’s first line-up was Wayne Mason and Carl Evensen (The Fourmyula), Keith Norris and Clint Brown (Rebirth, Taylor) and Bruce Robinson (Face, The Pleazers). Rockinghorse released two albums of their own, and won gongs for Best Group and Single at the 1975 RATA Awards. The band's celebrations led to a year-long ban from the Lion Breweries pub circuit.
