Nino Rota's last opera, in three acts, libretto by Eduardo De Filippo from his own 1945 play, composed 1973-77 and premiered at the Teatro Nuovo, Spoleto, on 22 June 1977 at the Festival dei Due Mondi. Source: it.wikipedia "Napoli milionaria (opera lirica)" (https://it.wikipedia.org/wiki/Napoli_milionaria_(opera_lirica)), which cites Jonathan Brandani's guide for the Teatro del Giglio, Lucca, and his study of the revisions in Archival Notes 5 (Fondazione Giorgio Cini, 2020). A staged opera, so it is in scope.
