Take a 2,000 seater auditorium - take two well known bands and start sound checking each in turn - first up is to get a rough general mix and send the auxs to the stage monitor mixing desk/operator....at this point you then need to fine tune all the different parameters necessary for a sound to satisfy the band as well as expected bums on seats - its at this particular moment that I received a sharp tap on the shoulder from a female who was telling me to sit down as she couldn't see the band - incredulous as it sounds she had entered the venue with her husband and seated themselves right behind me on a closed sound check period - I had great pleasure in having security eject them - another time - an old guy came up and asked "Why was it so loud" - again, it was sound check time - I told him it was so everybody could hear it !!! - he went merrily on his way quite happy with my flippant answer.....what on earth is security playing at when people can walk in willy nilly on closed venues at sound check time ???? anyone else got similar stories.
