Finally!…a YouTube clip of Peter O’Toole‘s visit to “Late Night with David Letterman” earlier this week, plus his somewhat less musical visit to “The Daily Show” and his chat with Jon Stewart. Best Stewart moments are (a) O’Toole’s pronounciation of the name “Katherine Houghton Hepburn” and (b) the notion of a 5 pm glass of white wine and a cigarette.
