Hello, Orgers!

I recently saw this up for auction and was wondering if someone here has it and could please explain the content?

tracklist:

1. edit 2:25
2. album version 5:38
3. extended version 5:40
4. 12" remix 7:48

My main question was if there is a difference between trks 2 & 3?
I know it's only 2 seconds, but perhaps trk 3 is a totally differnt mix than what was on the 12" or album?

Thanks for any answers!!!
