I've been listening to "Vicino a Te" quite a lot, and this is the one.
One seems always to return to Callas. I received a comment here that said her voice did not deteriorate. It is important to remember that she retired from the stage when she was only 42, very young for such a big voice. In contrast Mirella Freni recorded Manon Lescaut with Pavarotti when she was 58.
