It's just as bad for the audience sometimes:-( I have been to concerts of all types, including ones where I have paid a considerable amount for the ticket, only to have people in the audience decide that they know better than the act!

Often the amplification sorts it out but I regularly find that screeches, whistles, foot stamping and hand clapping from the audience do not usualy enhance the carefuly rehearsed arrangement I have paid to hear.

I would certainly never condone a strict 'sit there and be quiet' attitude but some people just shouldn't be allowed out on their own...;-)
