Well, Aaron, now I'm a bit confused by the whole Snake Charmer thing. I received the 'Last Night a DJ Saved My Life' CD and the booklet says that this version of Snake Charmer was an exclusive promo release.
However, it appears to be identical to Snake Charmer (Reprise) from the Snake Charmer EP, going by what I have in iTunes. Admittedly, I have the EP on vinyl but I got the MP3s from someone else. The running time is 6:54 which corresponds to what you have in the disco.
I also have 'The Sun Does Rise' EP on CD, and the version of Snake Charmer (Reprise) on there is a decidedly different mix. I guess I will have to pull out the vinyl to see which version of the track is actually on the Snake Charmer EP.
At the very least, I think we can safely say that this is the only CD release of this particular mix.
I also picked up Modern Mantra by DJ Spooky. The version of Stone's Eggs on there appears to be just an edit of the album version.
We're getting quite esoteric here, methinks.
