Question about Tokorozawa's Bootleg (Space Boogie)

I've been listening to this bootleg for quite sometime and noticed with official and other audience tapes. Space Boogie sound a little slow and darth vaderish. The official release sound matches the other audience source but nothing mathces Space Boogie when it comes to the tone of the concert.

Yup, the tape does run a bit slow. Pretty common problem for analog.

When I can get my computer to stop acting up I'll work on remaking my source mix with a speed corrected version of Space Boogie.
