I learned this from an old home recording of Angus, which was thoughtfully put on the internet:
He goes into the polka at about the 2 minute mark. Probably I’ve missed a lot with the transcribing here as I’m far from an expert, indeed I’m pretty atrocious at that sort of thing! The only other recording of this fun tune around I think was on a disc from another great Cape Breton fiddler, Carl McKenzie, "And His Sound Is Cape Breton." For completeness here’s his take: https://app.box.com/s/40zmog75dusnvbaek9xx I really don’t think I’ve caught what Carl played, so have a listen and modify accordingly if so desired.
Actually listening to Angus again I didn’t do half bad, Carl had his own setting here. I should say that Mary Jess MacDonald keeps right up playing the tune on the piano too. They go into the Iona March next. Someone should transcribe Angus’s playing of Listen to the Mockingbird, too. ;) Have to get that going on the banjo…
