Alexander Wright and Phil Grainger’s regular Fringe runs have won them legions of fans over the years. This is their first ever family show, performed in a brand-new Fringe space in the State Library, just around the corner from an expanded Courtyard Of Curiosities At The Migration Museum. Obviously, there’s no better place to share a story than a library, and the show’s simple set feels like a natural part of the space. (If the sensory bells and whistles of some children’s theatre is too much for your wee one, this show is ideal; although audience participation drives much of the action, there’s no pressure to join in and the whole thing is gentle and approachable.)  

Adults who know their Greek myths may wonder why it’s Poseidon’s turn in the Wright and Grainger spotlight, but who understands children better than a dude who fathered over 120 of them? He’s retired from godding now anyway, and the only vestige of his former life is a daily swim followed by some chips. That’s where he meets Kid, who needs his help to make sense of a grown-up world that’s changed around him. Phil Grainger rides solo and thanks to his music and keen eye for the details of family life, there’s plenty of emotional punch (some adults may even have had something in their eye at some points). It’s a cerebral experience, which may not work for very small children, but primary schoolers (particularly those with a penchant for mythology) will enjoy this engaging hour of storytelling.

Grandpa Poseidon, The Courtyard Of Curiosities At The Migration Museum, until Sunday 23 March, times vary.
