This neglected play by Alfred Fagon – returning to Hampstead Theatre after its 1975 premiere - is an anarchic, chaotic exploration of the lives of black Britons in post-60s, pre-punk King’s Road. The play’s fluid approach to character and narrative made it hugely radical in its day: those qualities, and some of its attitudes, make it hugely challenging now. But my God, the writing is vivid, and Dawn Walton’s production compelling. She draws.
