repeated bits throughout an album

[bryantm3]

i haven't ever listened for it before, but does underworld do this at all?
like recalling a similar chord or theme somewhere before in the album but not in the same song.

ie: genesis' (holden, stimpee ) 1976 album, wind and wuthering, contains many repeated themes all throughout the album, ie:
-'wot gorilla?' contains a reprisal of the instrumental from 'one for the vine'
- the end of 'all in a mouse's night' contains a reprisal of 'eleventh earl of mar'
-right before the time signature change in ...in that quiet earth' contains a different reprisal of 'eleventh earl of mar'
-afterglow, at the very end fade out, there is a reprisal of 'all in a mouse's night'.

if you've heard it, or have this album, i suppose you can listen for it and see what i'm talking about, but if you don't, you'll just have to guess on my description.

has underworld done this before on the same album? i know that rez contains a reprisal of cowgirl, but it doesn't really work since it's on a single. :/
push downstairs is a reprisal of push upstairs, i think that's one.
can anyone else think of any others?
