Spud,I remember singing a version as a kid with my mates, "Three German officers crossed the line Parlez vous Shagged the girls and drank the wine...."and so on and so forth.I wonder it the words are of the same ilk.
Thanks Sarah and Amos, I have them all in mind.
Meadow muskrat, I don't know "The Valley of the Shadow" but have already got John McCutcheon's Christmas in the Trenches on my list of later songs.
