There's been a few incidents during the years. I remember a show we did in Bogota, Columbia some years ago, when things got a little out of control. When we went on stage there were still people waiting in line outside. When we started to play things turned chaotic outside. People who were still waiting to get in started a fight. We got this info after playing the first song of our set, and the solution to it all was to go off stage after the first song, wait for everyone to pass the security control and then continue the show.
