A quick dash down under. There seem to be lots of Australian folk tunes, with Scottish, Irish and English roots. (Not sure about Welsh but the cultural links are strong so the tunes are most likely there.) All of which would probably work nicely on a banjo. I guess there are a few players on here who already have been mining this vein, so any other pointers? Tunes that you've done? Source material I could look for?
