Why, you can sing it to any ballad tune, of course. Ballad metre isn't also often ref'd to as "common metre" for nothing; & any ballad written in it can, notionally, be sung to the tune of any other. In that sense, partic tunes attib'd by convention to specific ballads are somewhat arbitrary, as I have often observed. But one still likes the idea of a special tune for each ballad, doesn't one. Nevertheless, as you say, Bronson's Fause Foudrage has sort of become assocd with W o W & the sky hasn't fallen.
