The biggest Wall Street mystery: Bud & Darien's love theme song.
The biggest mystery with this movie is the uncredited, yet significant track that accompanies Bud & Darien when they make love, and it appears in a few other scenes, too. It's not listed on the official soundtrack, or on the IMDB soundtrack page. The song is a very tranquil melody on the marimba, with some squelching Saxaphone in it.
Stewart Copeland replied by tweet that the track was not his. I've not been able to reach anybody else responsible for music in this film to see if they might know what it is.
So IMDB forum, I pose the question to you: Does anybody know the composer / title of this track?
