Here in Australia we have lots of "traditional" songs in that they spent their time doing the rounds of camps etc before being collected towards the end of the 1800's through to present. A lot of tunes came here in the 1850s with the gold rush and grew Australian stories. Many were music hall tunes that were played in the big gold towns like Bendigo and Ballarat and were taken bush by the miners. English miners who "made their pile" generally took their fortune back to England and it is quite conceivable that a song with an American origin could have arrived in England via Australia. It's possible that All for me grog" could even be one of these. I remember the Dubliners telling me that they learned it from a friend who had picked it up in Australia, but variants exist all over. The tune that comes to mind that sprouted many Australian songs is "The little old log cabin in the lane". I've always thought that was American. Does anyone know?
