One of my readers provided, via email, this response to my question on televising the Cav excerpt:
I think the reason they had the Cavalleria part in the Gala, and left in for the telecast, was that was the one opera Volpe knew as a child, having to sit there and turn over his grandmother's 78 records. It's been told to be the only opera recording she had, and he was the only one who had that "job."Yes, that makes perfect sense. Thanks!
So, makes sense, right? Part of the Volpe legend.
