Upon seeing this film, Richard Carpenter set about recording the song played during the wedding scene, For All We Know with his sister Karen. "Karen and I were in Toronto to open the show for Engelbert Humperdinck. We had one night off before opening and our manager Sherwin Bash suggested we see the film Lovers And Other Strangers. We enjoyed the film and noticed the song For All We Know which we recorded upon our return home. (It subsequently won an Oscar for Best Song of 1970)."Carpenters - For All We Know (Lyrics)
