I must admit that I'm a bit jaded as the first time I saw them was when War came out and there weren't more than thirty people there. In 1983 I/we (sisters) hauled our very young arses down to SoCal to see the US festival where they really were THE act. Unbelieveable. I saw them again at a free show at Justin Herman Plaza before bit quake here in 87 where they stopped traffic and shut down the freeway.
After that tour, we wandered into the hotel they were at (The Clift, SF) and Bono and Larry walked in and played in a very small hotel bar at the grand piano Just messing about really but fantastic all the same.
I was very lucky back then!
