I'm also a big fan of U2 and I definitely hear the influences on To Live Forever(The Unforgettable Fire-Joshua Tree-R&H era), some bits of Lifting Shadows(the last chorus, not the overall feel of the song), Speak To Me, The Way It Used To Be, Trial of Tears. Not to say they sound similar at all, I can't imagine U2 coming up with none of those or I Walk Beside You(actually U2 never done something that poppy as that song), but the influences are there. I remember picking out more, but right now I'm not listening to either. But I think the main influence U2 has is on DT is some of JP writing style, the whole spiritual/christian imaginary(am I spelling it right?) thing sometimes has similar points, again, not saying they are carbon copies or obvious.
As for the thread topic, I'm torn between A- and B+. I wasn't thrilled at all when I saw the setlist, but when I listened to the concert I was amazed, and I wasn't a fan back then, it was my very first exposure to a lot of songs, Six Degrees included and it floored me. Having two epics was amazing, but I think ACOS would've been overkill on top of the other two. Could it have been been better? Without the orcherstra, definetely, but since they had that they took full advantage. I thought Vacant followed by The Answer Lies Within was a beautiful moment and I don't like the latter at all. And I would've skipped SS but I understand why it's there. The intro of The Spirit Carries On doesn't work on relisten, but the first time was amazing.
Would I've chose the same songs? Hell no. It is unbalanced and everything, and Raise The Knife, as good as it is, is a poor representation of FII, so is Innocence Faded compared to Caught In A Web or Lifting Shadows to make it breathe a little, but still a great show so I can't complain about anything.
