"I personally mark that concert as the beginning of my loss of faith in the chamber-music audience. Here was demonstrable proof that they don't listen and that opinions about performance are made up prior to concerts based on who the composer is and how "important" he is in that small musical sub-culture. Had anyone really been paying attention I firmly believe they would have at least suspected something was not quite right."

I think you have to, in fairness, say exactly the same thing about any audience. There certainly are a lot of people out there who seem to think that Frank's turds were golden. "You sniffed the reeking buns of Angel, and acted like they were cocaine." Frank wrote bad songs, and great ones. He was an amazing improviser, and had off nights. He had incredible gifts, and very real weak spots. In short, he was human. So is his audience, and I don't see them as being, as a group, somehow more critical, astute, or savvy than a classical or contemporary chamber music audience. How many of them laugh when they read about this one incident and say "All right Frank!" and wouldn't have caught on if Frank had lip-synched his last show? Of course we will never know. Would they care? I think Frank asked that question with "While You Were Art", of the Ear Unit's audience on purpose, but also of his own audience by extension.
