The topics might not have been too hot, but "The View's" Sept. 7 season premiere wasn't without its share of fanfare. In addition to being the first new episode in a month, it marked Barbara Walters' official return since leaving the show to undergo heart surgery in May. And where talk show hosts return from medical absences, David Letterman is sure to follow.
