The only song with that title, that I know of, was written by Mickey MacConnell and his brother Cormac, concerning the Christmas Day informal truce along the frontlines during WW1 and of a young German soldier, who during the truce had sung the German version of "Silent Night" was then shot when the hostilities subsequently recommenced. If this is the song you are referring to may I suggest that you sign up as a member of Mudcat and then you can PM Mickey on his Mudcat name, Chordstrangler, or alternatively contact him on his website at : http://www.mickeymacconnell.com/

Good Luck with your search.
