Yeah, I think it's a lock that Kite is pretty much gone. I mean could anyone list a reasonable setlist in the HTDAAB Tour setlist thread that could contain Kite? I tried through possibilities and thinking of integrating the song in the setlist I came up with and I couldn't. I believe none of the other people filled it in as well, but then again some didn't even include SYCMIOYO.
As for the Sometimes Part 1 statement from beau2ifulday, this is what Bono had to say about Kite, which I feel pits it close to SYCMIOYO with respect to emotional connotations and the personal quality the song takes on and just thought I'd include this along with reasons why the two might not be able to coexist on a setlist.
INTERVIEW SNIPPET from the CHRIS EVANS BREAKFAST SHOW--
Chris Evans: "In a time of new media, that was the big idea" -- is written on this album. Obviously you now think that's not the big idea anymore.
Bono: Nope, that's the song "Kite" you're talking about there, that's a way of dating it. It's a very emotional song, "Kite," it's about letting go of somebody you love, we all have to do that, you know, whether it's a family or lovers or whatever, and I just wanted to put a date on it, it's no big comment.
