Unless I'm very much mistaken The one about the Streets of Rochester and Marlbro was written by Pete Coe - a long long time after World War One or World War Two for that matter.

As I heard it, since the tune was English before it got transported to Australia, Pete thought it'd be fair enough to use it for an English song.

And the swaggie would probably have been on the run because he'd been involved in a shearers strike, was how I heard it, and the troopers woudn't have been after him just for the sheep he nicked.

And didn't Banjo Patterson rewrite the words for the Billy Tea company himself? A man's got to make a living. Jolly? Well if he'd said "bloody" for the swagman and the jambuck, which would have maybe been more natural, people would have objected.
