soundtrack question again

I did see the movie several years ago and so don't remember the character names. I also have not purchased the movie CD. I am interested in the music that is playing when Robert Duvall is on the plane heading back to the U.S. and he is dreaming about a dance he has with the girl he met. The dance sequence is only about 1 minute but the music is great. I would like to get the original music that supports that scene if it is recorded and available in a longer version.
