& the Meteors, The La De Das, Madder Lake, Stevie Wright (ex-The Easybeats), Wendy Saddington, Ayers Rock, The Captain Matchbox Whoopee Band and The Dingoes. Guitarist-songwriter-producer Lobby Loyde (ex Wild Cherries, Purple Hearts) was another key figure, including with his band, Coloured Balls (1972–74), which gained a considerable following, despite media allegations that their music promoted violence by sharpie gangs (an Australian youth subculture). Loyde played an important part in the re-emergence of Billy Thorpe in his new hard-rock incarnation of the Aztecs. Loyde's solo and band recordings in this period had a significant impact in Australia and internationally; Henry Rollins and Nirvana's Kurt Cobain are among those who cited Loyde as an influence. Rock musicals were an important development at this time. The local production of Hair brought future "Queen of Pop" Marcia Hines to Australia in 1970. In 1972 a commercially successful and critically praised Sydney production of Jesus Christ Superstar premiered, which included Hines, Jon English, Reg Livermore, two future members of Air Supply, Stevie Wright, John Paul Young and Rory O'Donoghue. It was directed by Jim Sharman, who had international success as the director of both the original stage production and the film version of The Rocky Horror Show. Alongside the more obscure acts was a raft of successful pop-oriented groups and solo artists, including Sherbet, Hush, Ted Mulry Gang (TMG) and John Paul Young, who became the first Australian performer to have a major hit in multiple international markets with his perennial track, "Love Is in the Air" (1978)—a song which was written and produced by Vanda & Young, who were behind many of the big hits of the mid-to-late Seventies. The tail-end of the second wave gave birth to Skyhooks, who bridged the transition from the third wave into the period of new wave music acts of the late 1970s and early 1980s. On the Australian charts Sherbet had "20 consecutive hit singles to its credit", while Skyhooks had two number-one albums, Living in the 70's (October 1974, 226000 copies sold) and Ego Is Not a Dirty Word (July 1975, 210000 copies sold). Both acts toured the US but had limited success there, although Sherbet had chart success with their single, "Howzat" (1976), in Europe. The early 1970s also witnessed the first major rock festivals in Australia, which were closely modelled on the fabled Woodstock festival of 1969. The festival era was exemplified by
