"There's a whale, there's a whale, there's a whale-fish he cried" and "There's ice and there's snow and the whale-fishes blow" -- better not sing Greenland Whale Fisheries to the Prats.:)

I remember years ago hearing a recording of the Newfoundland ditty, "I'se The Bye", sung by a group from California who had corrected it to "I Am The Boy."

If the Prats and the Politically Correct get to you, sing the full version of Congo River, or The North Atlantic Squadron, or one of the parodies of Barnacle Bill The Sailor.:) I would change lyrics to suit no-one, and "God damn them all" is pretty tame compared to some of them I know.

(Northwest Passage is a better song than Barrett's Privateers anyway, but perhaps I am biased in that regard because I am Canadian and every tuneless pub band here insists on trying to bleat out Barrett's Privateers. Few of them are possessed of the deep, deep voices required to do the song justice.)
