  1. Why is this song not available anywhere except via the you tube upload? Not on i-tunes, not anywhere. Only in the last couple of years did the dvd come out. Marilyn does not sing it in concert and it seems it would be a very appropriate song for her and Billy.

  2. I remember seeing this movie when it came out in 1980 and I was living in Los Angeles. The story was very touching and based on real events in Neil Simon’s life, the loss of his wife and marriage to Marsha Mason. I remember being very moved by this song at the end title credits; it added immeasureably to my enjoyment of the film. Marilyn McCoo’s beautiful voice and this song have haunted me since 1980 and I hope its re-released by her on a CD.

  3. Coming across THIS beautiful Marvin Hamlisch song is the reason I signed up for a YouTube account- as to thank you. When I interviewed Marilyn and Billy a few years ago when they were guest artists with the Louisville Orchestra the first words out of my mouth were ‘Will you be singing the theme song from ‘Chapter Two!’ (She didn’t though) and I have been looking for it all these years. l loved the movie just as much. Thanks again.

  4. I have tried every conceivable way to listen AND purchase it…including writing to Neil Simon, Ms. McCoo & Marvin Hamlisch!! Chapter Two is a movie very near to my heart & I have been singing I’m Your Side to my husband for years!! He just purchased a new VHS player so I am again able to watch the movie. PLEASE continue your efforts to have it released and again, THANK YOU!!

  5. THANK YOU! THANK YOU! I loved this movie and loved this song so beautifully performed by Marilyn McCoo. I tried to find it EVERYWHERE. Neil Simon gave a talk in La Jolla some years ago and I so wanted to ask him how I could get this either in single form or album. Please release it again.

  6. THANX to all for stopping by…I have never received so many private notes, each of you telling me how long you’ve been searching for this Marilyn rarity. It was never released as a single but perhaps this special FOREVER 5th DIMENSION version will cast the spotlight back on this fan fave in a way that we can get it released in a special compilation one day soon!
