There is also a Scottish song on the same lines where a French ship wrecked off Boddam (S. of Peterhead in Aberdeenshire) and the sole survivor was the ship's monkey. The locals assumed this was a Frenchman, and since there was currently a war with France, they hanged it. I don't have the words but the title is "Yhe Boddammers Hanged The Monkey-O"
