I have a few. I'll posted a link to the Blacklab version of the theme song before the movie came out. I think that's the one dragon was thinking of. This song is in the same spirit as the movie theme song but I think it's about 3 times better.

They're all the same thing but the second one is a youtube link to the top video if you just need to save it for something. The third link is the cartoon clips spliced to the song instead of movie clips.
