Alright, just caught U2's excellent peformance of "Walk On" w/snippet of "Peace on Earth" in the beginning. Also noticed that there was an extra guitarist near The Edge. Not sure who it was. Eric Clapton? No. Dave Stewart from The Eurythmics? I'm not sure yet. Anyway, also caught 3 backup singers on the side...2 of which I can identify as being that of oddly enough...Morleigh "Bellydancer-Mrs.Edge" Steinberg and Natalie Imbruglia who was singing in the middle. It was a strong and passionate performance to say the least.
