Fake Fans During A Night In With Beyonce ?

Was it just me or were the audience/fans on A Night In With Beyonce very strange?

I mean they reacted like they had all won the lottery when she stepped out at the start of the show. Fair enough its Beyonce but things started to get suspicious when the crowd knew exactly what movements to do during the 'to the left, to the left' without even being told by Beyonce or even being hinted at what to do. Not only that, the camera would also always be on that one person in the crowd who was going 'way over the top' screaming and shouting during a Beyomce song. Fair enough a normal person would have a dance and a scream but it was just funny how these people were picked up just at the right time by the cameras only to flick back to Beyonce a few seconds later.

I may be completely wrong but it all looked a bit fishy to me. As if they had all been told what to do, when to do it and to make Beyonce look as good as possible.
