Richie,
I strongly suspect an older Scots recording of 'Wee Cooper' is the source. All of the versions of this title seem to vary very little if at all and must have a fairly recent common source. By fairly recent I mean early 20th century. I will check this out using my own indexes as mine contain more cheesy/popular stuff than the Roud index which has more respectable sources. It could for instance have been in the repertoire of someone like Harry Lauder or Will Fyfe.
