Cole Porter wrote the song "Let's Do It (Let's Fall in Love)" for his 1928 musical PARIS; Noël Coward wrote new lyrics for it during World War II when he was traveling the world entertaining Allied troops, and he kept updating them during his nightclub performances in the 1950s. So, it would seem a good basis for the beginnings of an anthology musical revue of the songs of Porter and Coward. Actually, though, the song is not in the show, which is an immediate indication that the effort, led by David Kernan, who has participated in similar evenings of the work of Stephen Sondheim and Jerome Kern, does not realize its potential. There are some good ideas, such as blending Porter's "I'm Throwing a Ball Tonight" with Coward's "I've Been to a Marvelous Party" and Coward's "London Pride" with Porter's "I Happen to Like New York." The balance of selections leans more to Coward than to Porter (of 28 songs sung in whole or in part, 17 are by Coward, 11 by Porter). Peter Greenwell (a former Coward accompanist) does a particularly good job on "Mrs. Worthington" and "Useless Useful Phrases."
