It doesn't seem to vary a great deal textually, except for the occasional garbling of the names, so perhaps hasn't moved very far from print sources. Four years on, I don't really know any more about it, and the image links at the Bodleian still don't work. It was obviously quite popular, and seems to have been the work of a hack broadside lyricist working in a conventional style of the kind used for many such songs throughout Britain and Ireland, presumably in the mid 19th century. The broadside examples we know of are Irish, and it has persisted there. It travelled on to Canada (where it was printed at least twice during the 1940s in the "Old Favourites" column of the Montreal Family Herald & Weekly Star), and thence -a little- into the Northern USA. Evidently it also lurks in Australia!
