Studio versions are far from equal and PopMart Please was the highlight of the entire show.
Just as Kite at Slane was the highlight of that show.
I thought SBS was the highlight of that show. One of the rare occasions that it was apt for U2 to perform that song.
But really, do you think Kite was the highlight of the Elevation tour? I thought The Fly was, along with UTEOTW. Both AB songs.
SBS is a close second for me. A very powerful performance of it, and the name-reading at the end was beautiful. But considering the emotions Bono must have been going through at the time, I'd say that Kite was way more important than SBS.
I don't think Kite was the highlight of the Elevation tour because I'd have to agree with you about UTEOTW and The Fly. Both stand-out songs performed at Boston. Kite just stole the show at Slane for me, more so than Please did on PopMart. That's why it got my vote.
