The soundtrack was moderately more successful than the film, peaking at No. 56 on the "Billboard" 200. Commercially successful singles were issued of both the title song, performed by Shawn Phillips, and "Living Together, Growing Together" by The 5th Dimension, the latter being the band's last top 40 hit on the "Billboard" pop charts. The song "Things I Will Not Miss" was covered by Diana Ross and Marvin Gaye during recording sessions for the 1973 album "Diana and Marvin". Tony Bennett recorded "Living Together, Growing Together" and "If I Could Go Back" for MGM/Verve. Richard Harris sang "If I Could Go Back" to the original musical arrangement made for the movie in the 1973 TV special "Burt Bacharach in Shangri-La". Herb Alpert recorded an instrumental cover of "I Might Frighten Her Away" on his album "You Smile The Song Begins".
