The other day I attended a terrific matinee of The Sound of Music at the Curve, Leicester – one of our most multicultural cities. White actors, a sea of white faces in the audience. Should it be penalised for a full house – perhaps the wrong kind – in a once-troubled venue? I think we need to take a more relaxed attitude. That doesn’t mean complacency, but it means we should also guard against art by diktat. The reductio ad absurdum of the Arts Council line is that we will need a greater percentage of dramas about Polish plumbers by 2018, and so far as quotas go, isn’t it time we worried about Jewish creativity being over-represented in musical theatre? Do we want to see patronising initiatives like “bring a black friend night” to the Royal Opera House? The huge generalising sweep of Suzman’s arguments aren’t very helpful but she’s entitled to relay what she sees going on anecdotally. And you know what? Maybe there aren’t any easy answers.
