How many non-album single-Acoustic Orchestras are there?

Either that, or it is just a fan work, but the fan would probably have to be "on the inside" to have access to the vocal track.

It seems like a very likely explanation. Perhaps the project never was finished because of the poor sales of the other remix albums released after RAINBOW.

But with the instrumental available, woulden't it be quite easy to make an almost perfect vocal track?
