the fondest memory I have from a U2 show is when I saw them at soldier field during the popmart tour. the show was incredible, even though I was a bit disappointed with the live version of 'staring at the sun' but I will never forget what happened during 'ONE' .... the entire concert I was dancing in the aisle, I had seats in the 21 row in the front section. and an old security guy constantly had to tell me to go back into my row. I figured that he was too old to appreciate the music of U2, and every time he left I went right back out to rock n' roll in the aisle. finally at the end of the show during 'ONE', (the song that converted me to a U2 fan) I just stood right outside the last seat with my zippo and took in the visual-mind-fuck! the song "ONE" reflects my animosity towards God, suffering from a career ending injury that turned my world upside down, I had no one to blame but God, then in the middle of the song, I found my self crying profusely, I couldn't stop. I felt like through the song I was having a conversation with God. I shouted out. . "did I ask too much, more than a lot, you gave me nothing now its all I got" when the old security guard approached me and instead of yelling at me like he had the whole show, he put his arm around my shoulders. we looked at each other and he was crying too! this old man, who I thought had no emotion and could not relate to the beauty of U2's music. I was wrong and I gave him my zippo and put my arm around him. and we swayed together for the rest of the song.
