When I was looking originally for the song I got a reference to it on a playlist being sung by someone called John Ferguson but the page was unreachable. I've since found a reference this version John Ferguson - After The Ceilidh on a playlist for Radio CJFX, Highland Heart of Nova Scotia. It's possible that e-mailing the radio station for a contact to John Ferguson could get the words.
(Searching in general hampered by French maritime son coming up a lot and a book Notes of a Maritime Son (which might have influenced the song, who knows?)
