The worst show? No show is perfect - it all comes down to the band, the sound, the technical elements, the crowd, your experience. My worst show was the 2009 Wembley#1, because of the crowd being aggressive, angry, very unfriendly, and talking loudly very near the stage. But from a pure performance level, some of the early PopMart shows were sloppy and some of the late 1993 shows were a band on near exhausted autopilot.
