Yes,I’ve read about Slim Dusty. I’ve read that he’s a much loved figure in celebrating Australia’s history through his music.I’ve also read that he’s seen Down Under as “owning” Waltzing Matilda in the same way that Kate Smith is seen as “owning” God Bless America here.
OTOH, one doesn’t get much more Australian than The Seekers; Judith Durham has one of the sweetest voices ever to grace a folk group.
