One for the music guru's :)

Ok my little band of Aussie detectives...you've 100% success rate answering my Aussie culture queries so far so here's another...music this time.
A lunchtime radio show here has played a really lovely song a few times over the last couple of weeks but the idiot presenter never says who the guy is. All I've managed to workout so far is that he's an Aborigne, I think they said once that he's blind, he's not singing in English (at least not the one they play) and sounds like only instrument is a guitar.
Any ideas
???
