Michael, I heard your comments about CARMELINA on the Broadway radio podcast, and your pointing out that the program indicates the time for the proceedings as "present day," while it is obvious that the events in the story had to occur in the '60s, less than twenty years after the war.
I think the "present day" setting relates to the conceit of this production. This CARMELINA is a "show within a show" - we are told in the very beginning of the show, and it is reinforced at the end, that the waiters and proprietor at a restaurant in San Forino are putting on a show telling the Carmelina story, and that is happening in the present. At the very end, Joey Sorge's character says (SPOILER) I believe that Vittorio and Carmelina were his grandparents and he even holds up a picture
of them. So, while the events of the show aren't in the present day, as you correctly point out, the show being put on in the restaurant for its patrons (and the
audience) is in the present.
