to the Gallipoli campaign "And The Band Played Waltzing Matilda" recalled the Celtic origins of Australian folk-country. Singer-songwriter John Williamson, (OAM) began to build his reputation as an iconic Australian entertainer with his 1970 performance of his first song "Old Man Emu" on New Faces (influenced by novelty works of Rolf Harris such as Tie Me Kangaroo Down Sport). It was the first of many popular songs employing Australian slang. In 1982 he released "True Blue" and subsequent works including Mallee Boy, the lyrical "Galleries of Pink Galahs" and reworkings of Australian bush ballads and folk songs earned him a permanent position as leading exponent of Australian country and folk music. In 1970, Tamworth's Radio 2TM organised the landmark Bicentennial Concert to mark the 200th anniversary of the voyage of Captain James Cook along the coast of Eastern Australia. The pioneers of Australian country music Slim Dusty, Joy McKean, Barry Thornton, "Smiling" Billy Blinkhorn, Smoky Dawson, Shirley Thoms and Buddy Bishop all featured in the concert which contributed to a revival of interest in Australian country music which had struggled for airplay since the arrival of rock and roll in Australia. The Tamworth Country Music Festival began in 1973 and now attracts up to a 100,000 visitors annually. In 1974, a popular cross-over artist Olivia Newton-John, (MBE), (OAM), received the Country Music Association's Top Female Vocalist award in the US, despite protest from American country purists. Her popular hits have included I Honestly Love You and Tenterfield Saddler by Australian singer-songwriter Peter Allen as well as country classics such as "Banks of the Ohio" and "Take Me Home, Country Roads". Aboriginal country Country music has been particularly popular among the Aboriginal Australian and Torres Strait Islander peoples, creating a sub-genre often termed Aboriginal country music. Jimmy Little was a pioneer, Georgia Lee was of the same era (1940s–50s). Dougie Young, Lionel Rose, and Harry and Wilga Williams and their band the Country Outcasts were very popular during the 1960s and 1970s. Gus Williams, Auriel Andrew, and Isaac Yamma were active from the 1970s, and the 1980s brought Roger Knox ("godfather of Koori music"), Warren H. Williams, Kev Carmody, Archie Roach, Ruby Hunter, Tiddas, and the Warumpi Band, among many others. Troy Cassar-Daley is among Australia's successful contemporary Indigenous performers. Carmody and Roach have employed a combination of folk-rock and country music to sing about Aboriginal rights issues. The book, documentary
