Yea, the first incarnations were really strong, particularly the ones from their broadcasts (the instrumental from '06 and the vocalled one from early '07) and then the track seemed to have been gutted. 'Tis a shame both couldn't have existed since the latter version, as affore-mentioned is almost completely different save for elements of the original beat.
I remain cautiously optimistic that their collab took a listen to the versions and steered them back toward the original...
