In my YouTube searches I have come across some dreadful films of some very great singers. I won't link to them. I wouldn't want anyone to sit gloating and laughing over these films.
One is a film of Maria Callas. Everyone knows that she did not age gracefully. The films don't give dates, but we know this must be from the post-Onasis era.
Another is of Beverly Sills. This film notes that a year later she retired. This is a much worse example, because not many really good films of Sills are on the internet. So we get this bad one, so people can make cracks.
I would prefer to remember them in their prime.
