What is the etiquette regarding standing at Wembley?

[WHL87]

Some gooners almost came to blows during the semi-final..sit down you tosser...stand up and support the team you c**** etc. Problem is as soon as a couple of people stand up you can't see the pitch..

Or has that fine old cup final tradition been replaced with "Ladies and gentlemen, now please twerk to Sweet Child o' Mine, or something :-(
