I had a small comment in passing: what is the difference between opera today and opera 50 years ago? It seems to me the main change is that opera doesn't have the same penetration into the general culture that it had before. Renée Fleming appears on David Letterman and at the Superbowl, but that's about it. Thank you, Renée. Comedy / variety shows where Beverly Sills guested no longer exist. Do we need an opera singer on Big Brother? Certainly the other guests wouldn't recognize them.
