If our Italian members (like
The Stranger or
Yure, etc.) don't answer you...I'll ask my girlfriend's dad. He knows everything about traditional, Italian tunes.
Over the holidays, I brought one of my "Crusade" DVDs along to play the song for my 'father-in-law'. He recognized the tune but didn't know its name!
The excerpt is brief but he definitely knew the melody & continued signing it.
Interrogating the uncle is next. Even though he is older, he has a sharper memory. Both of these guys are born & bred Italians who immigrated in the early 1950s (not like the generation of North American 'mangia cakes') so it's possible that the older brother may know the answer. An univestigated avenue...
For the time being, I've exhausted my resources so unless someone else solves the puzzle soon, I'll give it another shot in a couple of months.
