Den - got that one - but you're my first Northern Ireland report so far [which is astonishing considering the interaction between the North and Scotland).
Bob - you might know it would be Newfies - I was telling stories at a festival in Prince Edward Island last Sept and met a few.
Captain Swing - where where where did your mum come from, and when did you hear the song from her? [I need to try to establish chronologies as best I can.]
If it was sung to the Cock of The North tune it seems undoubtedly a source for the drawers element. Even if not it fits the bill so neatly. (It could be the other way, but the neat nature of your verses maeks that very unlikely.)
All contributors - I should have explained before now that at the age of 57 years I'm working on a doctorate on Scottish Children's Song, the working title of which is Auntie Mary Had A Canary. I'm working over my first chapter, using this song as an exemplar on how such songs are so often cut-and-paste remakes and reassemblies.
Thanks again for help.
