Betty Comden and Adolph Green were one of show business’s great partnerships. “We meet, whether or not we have a project, just to keep up a continuity of working. There are long periods when nothing happens, and it’s just boring and disheartening. But we have a theory that nothing’s wasted, even those long days of staring at one another. You sort of have to believe that, don’t you? That you had to go through all that to get to the day when something did happen.”
