Lange did do a remix of this track, but this is definitely the original bootleg using the 'Soulsearcher' vocals that Jules was spinning way before it got its full release in 2001.
I never did like the later Taka Boom vocals, I was used to hearing the bootleg version. A bit like when 'Tomcraft - Lonliness' got it's proper release and that had someone else singing the vocals, it really bugs me.
God I'm sad.
I reckon its Soulsearcher vs. ??? - Just Can't Get Enough
