Music used in Breaking point

I am looking for the music used in the movie Breaking Point (1989), and more particular the name of the performer (it was a ladie's voice) and the name of the song. As far as I can recall (I saw the movie twice, the last time more than 10 years ago) the melody was slowly jazzy and more or less sad . I was thinking about Dina Washington or Nina Simone, but these are just wild guesses. So if anyone can help me with this.
Thx
