Before this thread, the only times I ever heard "Auntie Mary Had a Canary" was from Newfoundland singers. Great Big Sea incorporated part of this tune in one of their instrumentals which receives a lot of airplay in Canada. I don't know the name of the tune or of the CD.My father played Cock of the North as I grew up in Nova Scotia while, at the same time, my buddy Garry learned it in 3000 miles away in Alberta. Based on this, I would guess it's played all over North America.
