I know this thread is old as hell, don't know if anyone will see this but worth a shot. I'd been looking for this track for so long too and assumed it never got a release. Just had another look and it was finally released in 2008:

It's also on Beatport, I just bought it:

I had no idea it was by JDS, I always knew it as 'Scorpion - Fire'. Really happy to finally have it after about 10 years lol, hope this helps someone if anyone is still looking for it!
