A thread on the American version is here and here are both versions. We still haven't found much solid information about the Australian version. Alan of Australia had promised a MIDI of the Australian versinon, but hadn't submitted it because he hadn't invented MIDITXT yet (hint, hint).
John of Brisbane seems to think the Australian tune is better and describes the original Stephen Foster tune as "martial," but that may be mere Australian jingoism on his part....
