Well, I can't know if the STM is the original original, but it's certainly more original than the converted mod. Most STM2MOD conversions that went bad just had bad samples, I could pull them, flip the bytes, reinsert the corrected samples, and all was peachy. This one was special because there were a few timing errors, a couple notes had to be corrected, and I never did find the right loop points (which makes the STM file superior).
Only a couple other conversions gave me half as much trouble.. Kefren's Funky (shortened some silent space at the beginning to match song timing, on top of sample fixes) and "Labyrinth" which had a similar problem. Funny thing, I recently found a STM of Labyrinth and it was missing the entire opening SFX sequence... that kind of thing sounds more like a mod to stm handy job to me than this*, but, whatever. I stopped being active after my BBS was crashed in 96 and I had a baby which took my primary focus, so I'm sure you've seen much more of this stuff than I.
Anyway, all that withstanding, I gave you the closest to original I have, so maybe people will actually enjoy the tune now.
* Edit: I just looked up your copy of Labyrinth.sfx.2 , and it that seems confirmed... I fully believe your copy is the true original of that one.
Edit 2: OMG I totally didn't see you had a link in there. Well, that's embarrassing.. on a brighter note, I now (once again) fully agree with you. I just really need to slow down sometimes. I wonder what else I can find actual original MODs of..
