On October 9 , 1993 , Hicks was scheduled to appear on the Late Show with David Letterman for the twelfth time, but his entire performance was removed from the broadcast -- the only occasion, up to that point, on which a comedian's entire routine had been cut after taping. Both the show's producers and CBS denied responsibility. Hicks expressed his feelings of betrayal in a hand-written, 39-page letter to John Lahr of The New Yorker. ^[5] Although Letterman later expressed regret at the way Hicks had been handled, he never appeared on the show again. The full account of this incident was featured in a New Yorker profile by Lahr. This profile was later published as a chapter in John Lahr's book, Light Fantastic. ^[6]
