Bli***y what a strange thread. Australia source of skiffle I think - Odd USA folk has it's most powerfull influence from - nope not Africa but Native America!! Listen to the old timey music. I suspect that Australia just like Merica takes much of it's rhythms from the native culture. Also why should any one claim 'ownership' of a music ??? Just a thought - if Heights of Alma is a tune who needs to own it and why????
