This is certainly probably the greatest liveconcert possibly! I really hope I was there in 2001.
How U2 sings togheter with the audience, is incredible!
It has a story this concert, Bono's dad had past away a few days before and Irland had beaten England in Soccer.
The emotion and feel deliverd by U2 is completely unprocessed!
