soundtrack.

Don't know if it was ever released on vinyl when the film came out, but you can buy it on CD here.

This soundtrack isn't complete, though, it's missing a song from a house party scene, the song that is missing can be heard playing in the background in this scene:

I've been trying to identify this song for years now in hopes someone will recognize it on the web.

But anyway, there's the soundtrack if ya wanna own it.
