 Among the brightest stars of early Australian rock and roll was Johnny O'Keefe, who formed a band in 1956; his hit "Wild One" made him the first Australian rock'n'roller to reach the national charts.While US and British content dominated airwaves and record sales into the 1960s, local successes began to emerge – notably The Easybeats and the folk-pop group The Seekers had significant local success and some international recognition, while the bands the Bee Gees and AC/DC had their first hits in Australia before going on to international success.The arrival of the 1961 underground movement into the mainstream in the early 1970s changed Australian music permanently.
