G'day Calach,That is quite a good Scottish Van Dieman's Land. the version in the DT marked Van Dieman's Land (Young Men Beware) is a pretty fair version of the English (probably original - see my posting above) version.
The one simply marked Van Dieman's Land and then headed Wild Young Irish Boy. is an incredible mélange of: Wild Colonial Boy, Van Dieman's Land, Henry Lawson's Trooper Campbell and Captain Starlight ... and God knows what. It even has a verse starting "Now, one morning in the merry month of May ...! I wish I knew more of its provenance - maybe to hunt down the author and put him out of his misery.
