What is that damn theme song called?!

I know a lot of people hate the use of music in this movie (especially the repetition of the track that plays off of Freres Jacques) but I would be eternally grateful and absolutely indebted to whoever could tell me the name of the theme song in this movie they play several times! The jazzy one that starts about 16 seconds into the movie, almost sounds like some Nicolai/Umiliani type stuff but is in fact Juan Calderon! I've looked everywhere and can't find this song or what it's actually called, anyone know?!
