It would be great if he joined us for a discussion.
Hey, maybe you can ask him who the old man was that was singing at Connie's wedding! Still say it's Nazorine's father.

When Mama Corleone is singing, at the 16minute and 35/36 second point of the film right before it cuts to Sonny walking up the stairs she says "Nazorine come here" and then motions with her hand. Nazorine then comes on stage with that person so it has to be a close friend or relative, Father would make sense since they could have the same name.
The one thing I can say is that the person is definitly not credited, on imdb they have the extended list of characters and anyone that says "Wedding Guest" or anything to that degree was born around the 50's making them late teens early 20's when the flim was made. That person needs to have been born around 1900's/10's.
Maybe Harlen can help us out with this one, I searched for this actor for hours and nothing
