Someone on another forum was asking about this today and now I'm wondering too. Key differentiator is the break starting around 2:25:
It doesn't sound like any of the official mixes I have, but there's nothing in it that would be out of place for a mid-'80s version either -- some of the touches are very ZTT-like to my ears. I think the rhythm tracks have been reprogrammed, which would point to maybe a remix service or bedroom remake?
And before you ask, I double-checked the obvious and it's not "The Final Story" -- at least not the version of that mix on the UK 12". I don't have the pictured Japanese 12" to check, though, and with a track with this many mixes you never know if someone sent out the wrong tape at some point...
