Sherbet was formed in Sydney in April 1969 by Dennis Laughlin on vocals (ex-Sebastian Hardie Blues Band, Clapham Junction), Doug Rea on bass guitar (Downtown Roll Band), Sammy See on organ, guitar and vocals (Clapham Junction), Clive Shakespeare on lead guitar and vocals (Downtown Roll Band), and Danny Taylor on drums (Downtown Roll Band). Initially they were a soul band playing Motown covers and rock-based material. Alan Sandow (ex-Daisy Roots) replaced Taylor on drums by July. Sherbet signed to the Infinity Records label - a subsidiary of Festival Records. The band's debut single was issued in March 1970 as a cover version of Badfinger's "Crimson Ships" - from that band's January 1970 album Magic Christian Music.  During 1970 the band played a residency at Jonathon's Disco, playing seven hours a night, four days a week for eight months. They were spotted by their future manager, Roger Davies. By March Daryl Braithwaite (Bright Lights, House of Bricks, Samael Lilith) had joined, initially sharing lead vocals with Laughlin who left the band a few months later. Braithwaite's former band mate Bruce Worrall (Bright Lights, House of Bricks, Samael Lilith) took over from Rea on bass guitar. By year's end the group undertook their first national tour. See had left in October to join The Flying Circus and was replaced by New Zealand-born Garth Porter (Samael Lilith, Toby Jugg) who provided Hammond organ and electric piano.  In 1971, Sherbet entered Australia's prestigious national rock band contest, Hoadley's Battle of the Sounds, and won the New South Wales final but lost the national final to Adelaide-based band Fraternity (led by Bon Scott later in AC/DC). They entered again in 1972 and won the national final, previous winners include The Twilights (1966) and The Groove (1968), which went on to achieve major commercial success.  Sherbet's first chart hits on the Go-Set National Top 40 were covers of Blue Mink's "Can You Feel It Baby?" (September 1971), Delaney and Bonnie's "Free the People" (February 1972) and Ted Mulry's "You're All Woman" (September 1972). Most of their early recordings were produced by Festival's in-house producer Richard Batchens, who later produced albums and singles for another Infinity label mate, Richard Clapton. The band increased its profile with prestigious support slots on major tours by visiting international acts including Gary Glitter and The Jackson 5.
