Carl Orff wrote a piece called Gassenhauer which has been used in a number of movies (Bandlands, True Romance, Finding Forester, etc)

In True Romance it's known as Your So Cool by Hans Zimmer. It's primary melody is played by a marimba.

So far I've found websites where other people are asking for this, but I haven't found anyone actually selling it.

Does anyone know where I might be able to find a copy of this sheet music? (Ideally an accurate transcription, but at this point I'll take what I can get).
