Don't get me wrong, I still appreciate the effort, but this is the official version; the b-side version that was later put on Sci-Fi Lullabies. The only difference is that it has a slight fade-in put on it and seems to be awash in some rudimentary reverb of some sort...but it's definitely the finished version.
Whoever you got this from labeled it "studio demo" and may or may not have been responsible for putting said effects on it...but it's really the b-side.
Thanks, though.
