They provided pop and rock songs for other recording artists, and for themselves under various stage names: Paintbox, Tramp, Eddie Avana, Moondance, Haffy's Whiskey Sour, and Band of Hope. The pair worked with Young's elder brother Alex in Grapefruit. Young and Vanda returned to Sydney in 1973 where they worked for Ted Albert, at his Albert Productions recording studio to become the in house producers. One studio-based group, Marcus Hook Roll Band, was joined in 1974 by Young's brothers, Malcolm and Angus. The brothers had already formed a hard rock group, AC/DC, in 1973. Young helped them with AC/DC, which went on to become a success internationally. He declared to his brothers "that he didn't believe a band can ever call itself a band until it's done at least 200 gigs". With Vanda he co-produced AC/DC's early albums, High Voltage (1975), T.N.T. (1975), High Voltage (1976), Dirty Deeds Done Dirt Cheap (1976), Let There Be Rock (1977) and Powerage (1978). Young briefly played as AC/DC's bass guitarist, early in their career. He and Vanda also co-produced the title track and two instrumental tracks on AC/DC's Who Made Who album in 1986 and the Blow Up Your Video album in 1988. Young alone also handled production duties for AC/DC's Stiff Upper Lip album in 2000. He also made the suggestion that "It's a Long Way to the Top" should include bagpipes after having heard that Bon Scott had played in a pipe band, not knowing that he was actually a drummer. In mid-1976 Young formed Flash and the Pan, initially as a studio-based duo with himself on guitar, keyboards and vocals, and Vanda on guitar and keyboards. They had local top 10 hits on the Kent Music Report Singles Chart with "Hey, St. Peter" (No. 5, September 1976) and "Down Among the Dead Men" (No. 4, July 1978). The group's ninth single, "Waiting for a Train" (December 1982), had lead vocals by their former bandmate, Stevie Wright. When the single was issued in Europe in April 1983 it peaked at No. 7 in the UK, No. 15 in Belgium and No. 26 in the Netherlands. Vanda & Young also co-produced work for Wright, John Paul Young (no relation), the Angels and Rose Tattoo. As songwriters they provided the three-part "Evie" (April 1974) for Wright, which became a number one hit in Australia. They co-wrote, "Love Is in the Air" (December 1977),
