If you follow the blue clicky provided by Barbara above you'll find my comments about Dennis O'Keefe's interpretation of Christina McPherson's tune. I provided one of my own with (educated?) guesswork as far as timing is concerned, but at least the notes aren't changed as they are in D O'K's version.
The Craigielea tune on my site is from "Two Hundred and Twenty Popular Scottish Songs". The copy I have was brought to Australia by my great grandfather in 1893, 2 years before the birth of Waltzing Matilda.
You'll also find some comments about the Fusilier, but you probably own the same source as I do.
