About 4 years back I was MC at a really good festival on the south coast. The festival consisted of some excellent local, and not so local artists, but the main atraction for the night was a well known and especially nice duo. I was forced on more than one occasion during that evening to ensure that no one pushed the limits. I was severe, but - - - I made sure that anybody who tried it on knew what was thought of them. You have to put your foot down - no matter who it is.
