Razzle Dazzle is the jazzy title of a new book about the history of Broadway by Michael Riedel, the New York Post theater columnist and co-host of the show "Theater Talk." The book, which was published this past Monday by Simon and Schuster, concentrates on the near death of Broadway in the 1960s and its gradual recovery.

New York Times theater critic Charles Isherwood joins us to talk about what Riedel suggests were the prime factors in the sagging fortunes of the commercial theater during the '60s. And he asks, how did it begin to recover?
