Query: Opera failure and performance to match

Presumably Opera D'Oro and Gala use unauthorized recordings, from the audience, at least up to 1970. The sound in this 1956 performance is so bad it is difficult to judge the singers. Gobbi and Corelli were stars, but you would not know it. Frazzoni is an unknown, doomed by the recording. Some mistakenly try to place this opera alongside the composer's works of genius. The Americanisms are hokey, the music could be rejects from Boheme, Butterfly and Turandot. The finale is affecting, but the opera's absence from the stage is condign.
