Adapting a Thornton Wilder play into a musical has notable historical precedents. His 1954 comedy, The Matchmaker, was, of course, the basis for Hello, Dolly! And in 1955, Our Town was transformed into a live television musical starring Frank Sinatra. Now comes The Seat of Our Pants, based on Wilder’s wildest work, his 1942 Pulitzer Prize–winner, The Skin of Our Teeth. Under the direction of Leigh Silverman, with book and score by Ethan Lipton, this faithful interpretation gets by on novelty in the first act, thrives on its merits in the second, and offers hope, if not structure, in the third.
