The version Squeezer has above is Tommy Flynn's version. Tommy didn't sing a chorus though. He sang the song as written (although the last two lines about rats and devils is sung as if it's a separate verse rather than an ending to a longer one) but repeated the first verse which we were then all allowed to join in with (no joining in with the rest even though we all knew it by heart in those days!)

It was sung at last autumn's Bangor Morris re-union (by Dave amongst the rest of the congregation) and will, no doubt, be sung again this year at the 50 anniversary of the founding of the team.
