Birdland is a night of rock stars for this theatre fan and @Polyg too I imagine. You see Simon Stephens is a rock star playwright for us and Andrew Scott is a rock star actor and the play is about a rock star.
Andrew Scott plays Paul who's playing to crowds of 75,000. He's reaching the end of a 15 month world tour where one country and hotel blends into another and there seems to be only two states of being: performing and waiting to perform.
Paul hasn't so much been corrupted by fame as badly tainted by it.
"I walk into a room. Far more people know who I am than I could possible know and after a while that does start to get a little disorientating."
He's a cash cow for so many people it's got to the stage where they won't refuse him anything and that money and influence is corrosive. He's living a surreal life and losing his grip on the real world. Money means nothing anymore other than being his answer to everything. Buy something to make himself feel empowered, buy things for others to make them feel better or like him or to impress. Buy things because he can and what else is there to do in between gig?
There are drugs and alcohol too - always the best and purest of course - but these are just part of the landscape.
Paul is a cock. Actually he's something stronger than that and he does admit it a couple of times when he manages to pull back to himself for a moment. The adulation and constant attention has made it difficult for him to make social and moral judgements. He is offensive and destructive when it comes to relationships and friendships.
