Welcome to the stinking, sprawling Bayou Mansions – the thorn in a prosperous city’s side, the “short-and-curly hair in the mouthful of sponge cake”. So cramped there isn’t even room to swing a rat (and there are plenty), so corrosive that everything here starts life as a bad smell. Forget the enchanted worlds of fable and fairy tale, this is a dystopian childhood fantasy masterminded by the select team of Kurt Weill, Kafka and the Wicked Witch from Snow White. As delicious as it is delicately malevolent, The Animals and Children Took to the Streets is a strychnine-laced gumdrop of a show, and slips down all too sweetly.
