Land of my fathers - my fathers can have it ! (Dylan Thomas)

Apparently few of the Welsh football team speak Welsh, and are therefore unable to sing the country's national anthem before the match. The Welsh manager has decided that this is not good enough, and has recruited the current Miss Wales to teach them the words.  If memory serves, didn't someone come up with a "cod" English version which was reckoned good enough to get by provided you were singing in a crowd?  I seem to remember it started "My hen laid a haddock...." but can't remember how it went after that.
