yes that's me. What I did in those reworkable versions was to speed up each track and when I did it I got the reach the correct tone. That's because the original leak versions are longer than mine reworkable versions just because the last ones are faster than the first ones.

This kind of thing happens when you transfer a cassete recording to a digital equipament and the cassete player needs to be fixed. So you'll find lots of Bon Jovi bootlegs with this kind of problem.
