Starchild, at the Oxford Playhouse on Saturday night, is a musical composed by Chris Williams about three young people who are transformed by a strange, celestial girl, writes Rose Hankey. She takes Bonnie, Mark and Wiktor on a journey of self-discovery through an icy kingdom, a grey factory world, and a desert of diamond miners. The show will be performed by a cast of 33 local children, aged 10 to 16. During the past two weeks they have undergone a transformation of their own into an acting, dancing and singing troupe with a thoroughly professional attitude. Director Fiona Ingram, Community and Education Animateur, has been encouraging them to think big, throw their voices like spears and "knock the audience over with the power of it!"
