Sinatra singing "At Long Last Love" in "Return to Me"

[Naphtali]

I am confused. In the romantic comedy, "Return to Me," starring Minnie Driver, Frank Sinatra sings "At Long Last Love." I have a copy of this precise version of this song - from a live concert in Paris in 1962. But the CD version is 2:12 in length while the movie version is close to 4 minutes. I strongly prefer the longer version and have searched for it to buy or download. It seems to exist only on the DVD of the movie. If I had the skill or proper utility application???, I could probably obtain it from my DVD. But I do not.

Does anyone know where the longer version can be found?
