I'd say no, as it happens. You already have TNSG, so I'd say go for a later one to hear a different sound. The Fall's sound has gone through so many stages - maybe a cheaper collection, like '50,000 Fall Fans Can't Be Wrong' or '458489 A-Sides', both of which can usually be picked up cheap.
On the other hand, check out posts number 180-190 on the sharing thread in this section. You should find download links for a couple of Fall shows, posted by Everyneurotic. 1988 and 2005, I think.
Beware that a lot of Fall stuff is semi-official and non-official compilations of live and alternate versions.
This discography is good for letting you know what's what.
