That is truly classic!
I think he was just so proud that they played a brand new song, and he didn't mess it up like he did with Walk On, so he wanted to remind everyone about it, and decided to sing a line of The First Time.
Regarding the "new" songs I heard tonight, here are my comments:
Walk On: obviously, far from the best version I've ever heard of this song. Hopefully they'll try it again tomorrow night, and we'll see if it turns out better. The "lyrics search" was comedy genious. Is there a video of the lyric search on the web yet? Imagine some comedy routine where a guy keeps looking at papers and tossing them on the floor. That was Bono tonight. Hilarious.
Miss Sarajevo: Wow, that was awesome! The ending was incredible. Beautiful stuff. I've avoided all the Euro bootlegs so far, so tonight was the first time I heard it. Just wonderful.
Old Man River snippet: not terribly exciting, sorry to say. Also, that Dakota Hills or whatever snippet was kind of surprising too. What the heck was that?
Discotheque: It didn't seem quite as exciting as it did on previous tours. The entire crowd seemed quite uninterested in it too. I'd vote to drop it and bring back one of the far superior Achtung Baby songs (either Zoo Station, Mysterious Ways, or UTEOTW).
The First Time: Holy Flapjacks, this sounded awesome! When Yahweh was mysteriously played during the main set, I just figured we'd get Fast Cars or OOTS. Boy was I surprised when they went into this. Its one of my two favorite songs off of Zooropa, so I was just in Heaven! A great song, and Bono was actually working on some audience participation during it, so I have a feeling they'll be playing it again on this tour.
