 He was widely touted as Australia's first singing cowboy complete with acoustic steel string guitar and yodel, in the style of American Gene Autry: Dawson had an extraordinarily long and prolific career, releasing his first single in 1941 and his last album in 2005, aged 92, making him at the time the world's oldest recording artist (now surpassed by Dame Vera Lynn who released an album aged 97, in 2014).
