Told almost completely through song, the play chronicles a love affair and marriage over five years, as Jamie Wallerstein – an up-and-coming novelist – falls head-over-heels in love with Cathy Hiatt, a talented but struggling actress. What makes this musical different is that Cathy’s songs begin at the end of their marriage and move backward in time to the beginning of their love affair, while Jamie’s songs start with their passionate meeting and move forward to the end of their marriage. As amorous or bittersweet as the story is, the core problem with these two characters is their basic immaturity. Nonetheless, the playwright has thrown in plenty of laughs — often in the most unexpected places. A terrific love story set to music.
