From Esquire T.V. viewers of the long-running, variety show Saturday Night Live rarely ever get a behind-the-scenes look at the speed and stress of what goes in to all of those set changes in that tiny, 8H Studio at 30 Rockefeller Center. The main stage where the guest host walks out usually serves as the same stage for the cold opening sketch.
