Although based on a seemingly foolproof formula, it was probably the ultra-commercial pop image that contributed to Cheek's eventual break-up. The mainstays of Cheek (Lee Emmett, Felix Maslin and Bud Mangion) first joined forces in 1974 as Jasper. The other members of Jasper were Peter Emmett (vocals, guitar) and Steve Hall (guitar). Jasper issued one single, `Lola', in early 1976 before calling it a day.
Emmett, Maslin and Mangion formed Punkz with the addition of Robin Jackson (original lead guitarist with Hush) and Randy Hall, who was quickly replaced by Ray Goodwin (ex-Dragon, John Paul Young and the All Stars). The band came to the attention of Ol'55 manager Glenn A. Baker, who helped mould Punkz's 1960s pop image. Mushroom issued the singles `Anyway You Want It'/`I Can't Control Myself' (December 1976) and `Take Me for What I'm Worth'/`Good Times' (June 1977), neither of which was successful. Goodwin left soon after and the band changed its name to Cheek to avoid any punk rock connotations.
A cover of the Mighty Avengers' `So Much in Love' backed with The Easybeats' `Do You Have a Soul?' was Cheek's debut single for Mushroom (January 1978). It reached #23 in Melbourne during April. Troy Richards (keyboards, guitar, sax; ex-Raw Glory, Rainbow) joined and Cheek commenced recording an album (which never eventuated). `Leave My Heart Alone'/`Still in Love' came out in June. It was not successful and the band broke up in August 1978. The four single tracks later appeared as an EP on Greg Shaw's Bomp label in Los Angeles. Jackson and Mangion joined the Chris Turner Band and Maslin joined Adelaide's Fat Lip. Maslin died as a result of an asthma attack in 1988.
