There's a song I have (can't remember where I got it) that I've searched for without success that isn't on the OST. It's very similar to "Time of the Dreamwatch" but it has some instruments in it that seperate it from the original (and in this case, sound better in my opinion). Since I can't post attachments, I don't know how else to let you hear it for yourself. It's definitely different than the original, but still the same with a bit of a different arrangement.
Sorry I'm not much help at the moment.
