Bellini - Beatrice di Tenda - Sutherland, Cioni, Elkins, Zanasi / Rescigno - Napoli 4 May 1962

This audience recording was not made with good equipment, there are pitch problems, distortions, sometimes muffled sound, but also clear passages.
Anyway this recording is a unique document in opera history and I am afraid that no better exists !
You can get a good idea of the performance. If the sound is disturbing for you, go to the Scala 61 Beatrice !
Siamo felici
