The transcription that I gave was from a photocopied page from a printed source (I believe from an Australian Broadcasting Commission songbook). The word on the printed page is 'back' although I agree that 'rock' seems more appropriate. I have learned that Larry King is most definitely Australia, but have yet to unearth anything further about him. I intend to use his song in a presentation of Australian songs at the Top Half Folk Festival here in the Northern Territory in June so I will continue searching for information about him.
