I had the full ride track...let me look for it. Did you want the old version or the new one at Disney now. I have the old version. You might also be able to youtube the complete ride and then covert the video to mp3.
If you use Firefox, there's a neat little add-on called "Flashgot"... install that. It allows you to save any media you find on the net... so like that last link is a quicktime page. With Flashgot, you just "Get Media" and it automatically downloads it to your compy... then open up something like Window's player and there it is. Ready to be uploaded to an MP3.
Edit: I'm assuming the song you are talking about is "Yo Ho, Yo Ho A Pirate's Life for Me"?
