Dance of the Vampires - 1999 Demo

There are supposedly 162 people who have this, and I've traded for about 30 copies of it. However, ALL of those I've traded for are cobbled together from others of the many Demos. Is there an actual Demo for this with these tracks specific to the release, or is this a "phantom" disc as cobbled together as what everybody is trading?

Hmm... mine seem pretty damn seamless and all are @ 128 ...?
