I'm new here, and the quickest way to make me like a place is a U2 thread. I'm positively obsessed with U2. My favourite song would have to be the live version of Bad that appears on the Rattle And Hum video. That is absolutely incredible.
My top 20 would look something like;
1. Bad (Rattle And Hum video)
2. Bad (Wide Awake In America EP)
3. Gloria (Under A Blood Red Sky EP)
4. With Or Without You (Rattle And Hum video)
5. The Electric Co. (Under A Blood Red Sky EP)
6. I Will Follow (Lido Beach, NY, 13/12/81)
7. 11 O'clock Tick Tock (Under A Blood Red Sky video, rocks the socks off the EP version)
8. Bad
9. Gloria
10. Sunday Bloody Sunday (Rattle And Hum video)
11. Where The Streets Have No Name
12. Walk On
13. Sunday Bloody Sunday
14. New Year's Day
15. Please (Popmart - Live From Mexico City video)
16. Springhill Mining Disaster
17. Heartland
18. A Sort Of Homecoming
19. Love Is Blindness
20. Gone
It must be noted that below the top seven or so, that's rather prone to change.
Personally, I prefer their earlier stuff - I have an electric live performance from 13/12/81 - although everything they do is fantastic. Well, nearly everything ... Miami, The Refugee, and Red Light are embarrassing. I've never had the pleasure of seeing them live, but on the videos I have, they're just incredible. My favourite video would probably be Under A Blood Red Sky: Live From Red Rocks, particularly for Surrender, Seconds, New Year's Day, Gloria, and 11 O'clock Tick Tock, although Rattle And Hum is amazing as well, with Bad and the fantastic mid-song Bono rant during Sunday Bloody Sunday.
In regards to Bullet The Blue Sky, I used to love the studio version on The Joshua Tree, but after hearing the live version on Rattle And Hum - and then seeing the actual video of it - the studio version just sounds lame. Bullet is simply incredible live.
And while talking about all things U2, my favourite U2 quote would have to be 'We thought that we had the answers/It was the questions we had wrong' - 11 O'clock Tick Tock. The guitar riff at the end of that song is amazing ...
