Good topic...I love POP and ZOOROPA is my single favorite U2 album. The latter, of course, is hard to translate live as it is heavily keyboard dominated. Additionally, my favorite song is Lemon, but the falsetto was a strain for 1993 Bono, so I'd imagine 2009 Bono would be singing a full octive lower. Hence, Lemon is not as high on my list as you'd think. Ranked by order in which they *should* see the light of day in a live environment:
1. Hold Me Thrill Me...a legitimate hit in its own right, would absolutely dominate with the current stage setup. Gone two full tours, definitely due to return.
2. Last Night on Earth...simply the best of many great Popmart highlights. A totally different song live.
3. Discotheque...was fortunate enough to catch its very brief token appearance on the Vertigo tour. Like most POP songs, translates well live and I liked the "rock" version of the Vertigo tour, they should have stuck with it.
4. Mofo...exactly the heavy-hitting material that could give some more heft to the setlist
5. If God Will Send His Angels...rehearsed and never really explored fully on Popmart.
6. Dirty Day...the gem of the ZooTV Sydney show. A powerful rocker.
7. Stay (Faraway, So Close!)...full band version w/Bono on acoustic, a la ZooTV. Never liked the Elevation version as much.
8. Staring At The Sun...great tune and legit 2nd single from POP.
9. Lemon...greatest song in their entire canon...but can they play it/sing it live?
10. The Wanderer...Cash tribute performance shows that U2 could pull this one off.
