I checked its details from windows media player: the version of Heroin in B-Sides & Abandoned Tracks compilation is 5:27 long. It's named as Heroin 12" mix (B-side to No Rest) 1985.
My question is about the 7" version.

Notice that the 7"/12" version of many tracks differs with the CD version - sometimes the 7" bside is a unique track/mix.
I have digitized my records, and discovered that I am missing a few of the bside tracks on CD. I now have quite a few 'Bonus' Bonus Tracks for my iTunes. (11 at present) *
Example: The Extended Mix of Brave New World - It was replaced on the 'Abandoned Tracks' CD and the liner notes even say so. The Extended Version that actually appears on the vinyl record has not been reissued.

I'm just curious about what's on the record - I'm told I can't have all of them.
RIP is a giveaway - every CD version is the Alternative Mix from the BNW 12" - I assume it's not the original version.
* By my count there are 14 in total - not too many, considering - still an album's worth of material though. (Wouldn't that be the most useful NMA bootleg ever?)
