that year and formed Sons of the Vegetal Mother (1969–70), again including Hannaford and Rudd, a group inspired by the work of Frank Zappa. 1970–1976: Daddy Cool and producing Skyhooks In 1970 Sons of the Vegetal Mother formed a side-project called Daddy Cool. The original members were Wilson, Hannaford (vocals and guitars), Gary Young (drums, vocals) and Wayne Duncan (bass, vocals), other members that joined, included saxophonist Jeremy Noone and guitarist Ian Winter. Known for their "good time" image, Daddy Cool's repertoire mixed covers of 1950s R&B and doo-wop classics with original compositions mostly written by Wilson. The band signed to the independent Sparmac label, co-owned by producer and former child prodigy guitarist Robie Porter. Daddy Cool became very popular in Australia and their records also gained a following in the US and Canada in the early 1970s. They scored a nationwide No. 1 hit in Australia in mid-1970 with the single "Eagle Rock" and their debut LP, Daddy Who? Daddy Cool, also reached No. 1 to set a record as the biggest selling Australian album to that time. The "Eagle Rock" promo was directed by Chris Löfvén who had earlier that year directed the video for Spectrum's single "I'll Be Gone". Around this time Ross and wife Pat both appeared naked in a short film directed by Chris Löfvén titled "The Beginning" which is an extra on the DVD release of Oz. After Daddy Cool broke up late in 1972, Wilson and Hannaford formed the short-lived Mighty Kong which included former Spectrum drummer Ray Arnott and Company Caine guitarist Russell Smith. They recorded only one LP, All I Wanna Do Is Rock released on Porter's new label Wizard Records, but the band broke up soon after. Whilst performing with Mighty Kong, Wilson was impressed by a fledgling Melbourne band called Skyhooks and signed their main songwriter Greg Macainsh to his publishing company. Daddy Cool made a surprise reformation for the January 1974 Sunbury Pop Festival and remained together until late 1975. Also performing at Sunbury in 1974 were Skyhooks and, despite being booed off stage, Wilson recommended the band to Mushroom Records boss Michael Gudinski. In June / July 1974 Wilson took time off from Daddy Cool and produced Skyhook's breakthrough debut album Living in the Seventies, which overtook Daddy Cool's first album to become the biggest-selling Australian LP. He went on to produce their next two albums, Ego
