I'm surprised by an aggression that is aimed at reading what people have to say on this thread rather than 'contributing'. What people say has an influence on what I can suggest to the curators at the Museum. I would like to add that my personal interest is in contemporary traditional Aboriginal music from the northwest of Australia - eg balga, junba, wangga. You can see by the questions raised in this thread that to define what an Australian song is, is not simple, let alone what might be 'influential'. Does that mean poplular? If so then it seems that one of the most popular songs has been "I was dreaming" by Juncker which had sheet music reprints from the end of the 19th century to the 1940s. But did that song influence people and whose voice was it? I am looking at Union songs, Folk songs which include songs from Italian, Greek, Macedonian, Vietnamese, Chinese, and other nationalities, Protest songs, Country songs and Pop songs. And I am sure I have not covered every possible category here. And I admit, to date, I am none the wiser how to help define this huge area - so I am listening to see what people have to say. It has to do with people's voice and how they use song to make their voice/s heard. That is what I believe this thread may be contributing to.
