It started much like the way it ended for David Letterman. There he came, striding onto the stage at the Ed Sullivan Theater on Monday night, to a standing ovation and a chorus of chants of “Da-vid! “Stephen,” Mr. Letterman said as he sat down. Mr. Letterman has been no stranger to the limelight since he stepped down from his late-night gig. He has done Jimmy Kimmel’s ABC show several times; Seth Meyers’s late night show; Ellen DeGeneres’s daytime talk show; Howard Stern’s radio show; Dax Shepard’s podcast; Marc Maron’s podcast; Conan O’Brien’s podcast.
