Last night (10/6/04), HBO ran a film with a great closing track, a blues number with a female singer, and behind her was merely a Rhodes piano, bass and drum.  I thought the title might be "Heart of Mine," but I wasn't sure.  I tried to read the credits, but didn't know the name of the song; but I noticed that David Baerwald was the consultant on the film. 

I'd like to get a copy of this song, but I don't know who did it or what the song title is. 

Any help would sure be appreciated.  Thank you so much for any assistance.
