They’re Playing Our Song is a 1979 musical with book by Neil Simon, lyrics by Carole Bayer Sager, and music by Marvin Hamlisch.
Based on the real-life relationship of Hamlisch and Sager, the show portrays a wisecracking composer teamed up with a new, offbeat lyricist. The match isn’t a good one at first, but after the two overcome a number of hurdles they find true love by the final curtain.
They’re Playing Our Song opened on Broadway on February 11, 1979 where it ran for 1,082 performances. It starred Robert Klein and Lucie Arnaz (in her Broadway debut). It received four Tony Award nominations.
