Charles Fox's music score, featuring flutes, harp and flugelhorn set to a contemporary pop beat, provided the "love" ambiance, which tied the stories together as a multifaceted romantic comedy each week. For the first season, the show's theme song was performed by The Cowsills. Beginning in the second season, the same theme song was sung by the Ron Hicklin Singers, also known as the voices behind The Partridge Family (based on the Cowsills), among others, featuring brothers John and Tom Bahler (billed as The Charles Fox Singers). This second version of the theme was carried on for the remainder of the series, as well as on most episodes prepared for syndication.
