Ezio Pinza - Catalogue aria from Mozart's "Don Giovanni" Video

Ezio Pinza sings the Catalogue aria ("Madamina, il catalogo e questo") from Mozart's "Don Giovanni." This must be a rarity for Pinza as it is Leporello's big aria in "Don Giovanni." It was recorded for a 1945 NBC radio broadcast. Donald Voorhees conducts his studio orchestra. Sorry for the poor sound; it's off a 16" glass-based acetate radio transcription disc only recorded at 33 1/3 rpm. On top of that my source is an MP3 file. I don't understand how people can listen to MP3 files when the sound quality is so shitty!
