Sorry, Mario, I've never heard it sung. But looking at the words you could sing it to the tune of The Lincolnshire Poacher or just about to Landlord fill the Flowing Bowl or The Song of the Western Men" (And shall Trelawney live, and shall Trelawney die....) and probably many other tunes.Verse and chorus are both 8.6.8.6, so any C.M. (Common Measure) or D.C.M (Double common Measure) hymn tune would also fit (my hymnal lists over 120 - Now Thank We All Our God, O Little Town of Bethlehem, etc, etc).
WassaiL! V
