Well, this is not as easy as it might sound, but: "ZOO TV"-version wasn't "ZOO TV"-version! In `92 indoors (and in the US outdoors, too) Bono still played the 2nd (acoustic) guitar, that gave the song a perfect sounding like in the late 80ies. Of course so he concentrated more on singing the tune than dancing cheek to cheek with some hot girlie. And, yes, we had the beautiful "shine like stars" part, too - which was rather usual these. These long versions had a different, though really great ending - a new, dramatic guitar solo by The Edge showing his skills.
On the other hand, the version got shorter during the last shows in Europe '93 - becoming one of the last McPhisto's flashes before the show ended under the stars, as you heard perfectly in Dublin for example.
In '97 the drummung and general sound wasn't that convincing anymore (the first shows even had a completely new electronic drumming experiment!) - and the singing wasn't that nailed anymore as before, too. Although I saw U2 performing a few astonishing and highly emotional versions of the tune, too - also inserting the "Love Will Tear Us Apart" snippet...
But the lowpoint of this THE JOSHUA TREE classic was definitely the last tour being more a "woooo-oooo-ooo-oooh" singalong of the crowd and sandwitched in the encore after "Bullet The Blue Sky" and before "One". Not a good idea at all, so I was really glad it was replaced by the really inspired "What's Goin' On" on the 3rd leg....
On the current tour, the tune is much more nailed again, regaining some of its moments plus a really strong vocal and band performance - but still lacking the last kick of the missing lyrics or snippets. But we're on a very good way, so let's see, what the future will bring ...
