Stew, I have to disagree with the label of A.L.Lloyd singing "The Murrumbidgee Shearer" that you linked to - it is definitely Gary Shearston in his folk-sheep-shearing-Lloyd style of singing, as on that whole LP of "The Springtime It Brings on the Shearing"!!
I still have my LP and absolutely loved it years ago :)

Cheers, R-J
