I was walking down an aisle at a large concert and U2 or just Bono was playing from a seat in the audience. I sat down behind him and kinda nodded hello. There was an open space next to the seat and then another seat where Bono 15 years younger with long hair was sitting. The Bono that was playing started talking too me in between verses of the song and while playing guitar. He was nodding toward the open space but I couldn’t really understand what he was saying though I tried. I thought maybe I was sitting in someone else’s seat and maybe he wanted me to sit in the open space but I couldn’t make it out. He finished his song and turned around. The other Bono pulled out a lawn chair and set it in the open space and sat down in it. Then he pulled up a large box and started pulling out sleeveless basketball tees. He had them in white, red and black with yellow numbers.  I asked for a medium and he gave me a red one with the number 5 on it. Then I saw my co-worker Issac walking by and wondered if I was in his seat and asked him if he wanted to sit down but he seemed to be focused on something else.
