Gore Vidal on Charlie Rose, 1998.
Starts at 2:37. Haven't watched it yet; not sure how annoying Rose will be. [Later:] Yeah, Rose is typically annoying. Asks the same five questions; won't let anyone answer them. Made a career of this. Ah, well. The Smithsonian Institution, a great novel, is discussed at least, when Rose can shut up. Great words of wisdom (do I need to say, from Vidal?) at 18:17.
