Charlatan?
Couple of mine. There were people filming the whole thing through their phones though, which was chuffing annoying.
Not as annoying as the coked-up cretins I was next to at the start of the gig who just kept shouting "hello Dave" every 10 seconds, whilst kicking and punching everyone around them.
You must have been right next to me at the gig!
