Phenomenal. Absolutely amazing to see them in their hometown, with 80,000 passionate Irish fans. My favourites were Sunday Bloody Sunday (the Irish pride and spirit was overwhelming!), Where the Streets Have No Name, and One. The light was incredible as the sun went down, and the tradition of asking everyone to hold up their lit-up phones, so that the whole stadium was glittering, was magic. It was, without a doubt, the best concert I've ever been to.
