Australian band GANGgajang formed in 1984 after Graham ‘Buzz’ Bidstrup and Mark Callaghan fell into a songwriting partnership during work on the Australian Broadcasting Corporation’s highly successful series Sweet and Sour, for which Bidstrup was the associate musical director.
Most of the band members had considerable experience in other bands. Bidstrup was with The Angels from 1976 to 1980, as was the band’s bassist, Christopher Bailey.
Guitarist Mark ‘Cal’ Callaghan was formerly frontman of The Riptides (whom Bidstrup produced) and keyboard player Geoff Stapleton served time with the Melbourne band The Aliens and Sydney dance band The Rockmelons before joining.
