Brixton Calling at Southwark Playhouse Borough review: a great London story, told with brio

Amazingly, in Runham, Lagan has found an actor with similar physical traits, who is also a musician with a decent singing voice. Sitima, meanwhile, is a multi-instrumentalist with a larger-than-life presence. Which is fine, as the two main characters are broadly drawn and the supporting cast – from Simon’s overbearing dad and his genial minder to various criminals, chancers and oddballs – are little more than caricatures. The musicians don’t feature as people: they’re gods dispersing ambrosia through the PA system.
