The question of this new You Too is:
You Too: What do you think is U2's signature song? (of these songs)
- Beautiful Day
- Where The Streets Have No Name
- I Still Haven't Found What I'm Looking For
- New Year's Day
- Pride (In The Name Of Love)
- Vertigo
- Sunday Bloody Sunday
- With Or Without You
- One
- I Will Follow
We'll leave it to you how a signature song is defined. You could think of it like what is the first song people would associate with U2
Please vote on the frontpage of the website, in this topic you can tell us why you voted for your answer.

It is, of course, the live version I'm referring to...
