"Roygbiv - Alphaquest Mix" was a remix done by BoC specially for someone called Andy Soosay's student film. The track was leaked onto the net and is understood to be genuine. It's longer than the original at 6:23. The mix begins with the track "Bocuma" in its entirety. It's backed up by images of the actual DAT inlay which contains nuggets such as "Custom DIY job for Andy Soosay", "Date Time: Thursday 15th May 1997", "SOURCE: Brown source or tomato source" and "COMMENTS: Yeah, it's pretty good"
Turns out we were putting Lead into the wrong thing all along.
