I know all of Sylvia Tyson's recordings well, and this is not one of her songs.I have also checked with Mike Regenstreif at CKUT in Montreal. He has been a great resource of information for me and lots of other people. He's also never heard of this song.
I repeat my suggestion that Roger in Blatimore was probably remembering incorrectly when he said that the singer was Canadian.
