NEW YORK (AP) – At least for David Letterman and Jimmy Fallon the show must go on. Both did their late night shows last night without studio audiences. Letterman and Fallon originate their shows in New York, which was taking a pounding from Hurricane Sandy. Fallon opened his show on the street in front of his studio. He told viewers he hoped they were safe at home and explained they were going to tape the show in an empty theater. Jimmy Kimmel canceled a planned taping in Brooklyn.
