Front cover is a close-up picture of part of the wall just about falling apart.
First show of 'The Wall' Tour and you can tell. Lot's of things are clearly 'first-performance' errors. During 'Empty Space' a curtain caught fire, which made Roger stop the show in order to have it put out. In The Wall Part 3' is a very long version with some great jamming in the middle. The band had to extend this song for a few minutes more because the brick-builders ran a little behind.
