Hey Spaw - are you talking to me or Mbo? I took genres to mean any field. And if Nixon, Hitler, and Socrates weren't performers (all of the Sara Bernhardt school of over-emoting, I will eat my autoharp). Sorry Mbo but Paul Robeson and Anity Bryant still fit.

OK I'll bite. When did you try to apply the statement to other performers and who were they? And what has this to do with Joan Baez? An opinion of whom you have not given. (trying to keep my language precise).
Love you,
Mary
