Ironic that this should come up today, having been asked to leave a concert because my hyperactive daughter was trying to sit on four seats at once and started to yell when we held on to her.... Politeness is a learned thing, and I got really quite annoyed, especially as the performer asked us to leave, and didn't say a word to the person five seats down, who'd been stage whispering to her partner all through the first three numbers..... I agree that noisy people should be asked to quieten down or leave, but if that happens every where at every occasion, then how is the person, be they child or adult going to learn that their behaviour is antisocial and that this is the way it should be done.... Besides, that is his future audience he threw out, I guess I shan't be paying to see him again with my family.....

And one of the biggest concert venues in London, the famed and fabled Hammersmith Odeon (now the Labbats' or London Apollo) STILL has a policy of letting people in DURING performances.
