They're Playing Our Song is a musical with a book by Neil Simon, lyrics by Carole Bayer Sager, and music by Marvin Hamlisch.
In a story based on the real-life relationship of Hamlisch and Sager, a wisecracking composer finds a new, offbeat lyricist, but initially the match is not one made in heaven. The two undergo a series of trials and overcome a number of hurdles before finding true love by the final curtain.

They're Playing Our Song is essentially a two-character show. Vernon and Sonia are the sole characters on stage; a Greek chorus acting as their inner voices is heard from the wings, and there are no big production numbers.
