Well, I know that "Zoo Station" works great live. I really enjoy "Lemon" live as well. As "MoFo" does. But it doesn't erase the fact that they were heavily thought/worked in studio and the fact that it all shows up in their respective records.Zoo station isn't a studio piece. Miss Sarajevo and UF aren't that hard to do live. Mofo/Daddy/Lemon had more work involved, but only Mofo worked live and arguably bettered the studio version.
Fez would be most likely somehing like Zooropa: cut down song, probably starting at Bono's howl that opens Being Born and skipping Fez. It could be done, it just isn't a live piece. COL is way too slow - think Your blue room or Miss Sarajevo bathroom breaks en masse. I like WAS and hope it makes the token acoustic song spot, but can also see why the band would rather stick to Stuck or Stay.
Why not give the Stand up comedy riff a chance instead ? It would work very well live and would be better than the studio version.
Still it doesn't stop U2to think in a way to play it live. If not, what's the point of conceiving and to compose a song, record it and work it a lot in studio, put it on a record and not play it? Keep it in a window of a shop as a delicate piece?
