Believe it or not, I can afford National Theatre prices and yes, perhaps even Royal Opera prices from time to time. I am capable of making an informed choice and could just about cope with an otherwise white audience. I work with white people, I dine with white people but I'm not particularly interested in this type of theatre. I do not go because I do not want to.
Reducing ticket prices is a worthy aim but I am not a barometer for the success or otherwise of Mr Robinson's social engineering.
