Joy Division live at The Factory

I was looking at my Heart & Soul box set today ( which incidentally, unlike Retro, has not yet fallen apart) and noticed that the Live at The Factory gig on disc four has 10 tracks. I see that the remaster version of Unknown Pleasures has twelve from the same gig, the extras being Shadowplay & Transmission.

Does anybody know why these weren't included on H&S and has anyone bought the remaster just to get these 2 tracks ? Also, has this gig been cleaned up at all for the remaster or is it essentially the same ?

?

(I'm still thinking about buying it.......)

For the quality issue, it's just the same.

And I think they wanted to include a few songs from other gigs, so they left Shadowplay and Transmission off. Shame really, because Transmission here is one of the more energy filled versions I've heard from bootlegs.
