Some of us seem to be confusing gigs with festivals, also small festivals with big ones! Obviously it's very rude to phone, text, take calls etc in a room or right up to a place like the Royal Festival Hall. I switch the thing off in any indoor place where one sits down.

But I do hope we're not extending this to open air do's like Cambridge or Cropredy. I was at the latter last weekend, along with friends from all points of the compass. Mobiles have made life much easier in these circumstances.

Also, as Ian says, if you remove one distraction they'll find another. I was mortified years ago when a girlfriend insisted, while in a seat in the second row at the Shakespeare Memorial Theatre, on following the action by reading the play from the Complete Works - and moving her lips. She had Judi Dench right in front of her for God's sake!
