In a single bound, David Letterman seemed to leap the full length of the stage at the Ed Sullivan Theater, racing from backstage as if he’d been thrust forward by the fanfare played by his longtime bandleader, Paul Shaffer, and his CBS Orchestra, and by the rumble of his announcer, Alan Kalter, bellowing his name — “Daaaaay-vid Leh-terrrr-maaaaaaaan!”
It was a routine Mr. Letterman, 68, has performed countless times but will repeat no more after May 20, when he will preside over his last episode of “Late Show,” the CBS franchise he established and has hosted since 1993. Like the veteran slugger who comes to the ballpark for batting practice, he was here on this April afternoon partly to warm up his swing on a few easy pitches, but mostly to put on a show.
No home viewers were watching as he twirled his microphone around like a Wild West lasso, walked it across the floor like a dog and leaned on an expensive broadcast camera. This was a pretaping ritual Mr. Letterman was doing only for the few hundred audience members in the theater. Or maybe he was doing it only for himself.
