Calvert G. DeForest, who appeared originally as Larry "Bud" Melman on David Letterman's late-night show on NBC, then under his own name when it moved to CBS, died Monday in Babylon, Long Island, NY at age 85, it was disclosed Wednesday. In a statement, Letterman, whose staff members originally found DeForest working as a file clerk after first spotting him in an NYU student film, said: "Everyone always wondered if Calvert was an actor playing a character, but in reality he was just himself -- a genuine, modest and nice man."
