Looks like my suggestions about the similarities between "Riding on a donkey" and "Bonnie Hieland Laddie" have already been preempted, although I've always heard the former played in a major scale and the latter I learned and sang in a minor scale. Both appear to refer to aspects of the Transatlantic timber trade.

How about the ultimate place name song written by Nova Scotian, Hank Snow?

I've been everywhere

Well, Hank's song (like the ones from the US and England and other places) is subsequent to, and a parody of the one sung by Lucky Starr that deals with Australian place names. Currently, Hank's effort appears in the DT while Lucky Starr's doesn't.

I seem to recall a lovely strathspey that tunefully recalls the eddies and pools of the St Lawrence River but I'm not sure whether it has words written to it.

Cheers, Rowan
