You may know the film which starred Brad Pitt. Forget about it. You may know the F Scott Fitzgerald short story on which it was based. Forget about that. Jethro Compton has relocated The Curious Case of Benjamin Button to Cornwall in the 20th century and has probably created one of the best British musicals of the past decade.

What’s the story? Don’t be put off if I tell you it’s about someone who is born old and over the next 70 years becomes younger and younger.

Think of it as a grown-up fairy tale or simply an excuse for an evening of rousing folk music about love and belonging.

The multi-talented Jethro Compton wrote the book, the lyrics to the songs, designed the set and directed the show. Talking of the set, it comprises rough hewn timbers salvaged from Cornish beaches that, put together as a floor with ramps and stairs and ropes, segues from streets to a pub to a ship. The story is told by the so-called Strangers, played by the talented ensemble of musician singer actors. Each plays specific parts as required but together they are phenomenal.

John Dalgliesh is the de-ageing hero.  He doesn’t reverse age by use of makeup, he simply carries himself differently. And in theatre that’s all we need, isn’t it? Because he’s different, Benjamin is rejected by his parents , which leads to him being uncertain about his place in society. Time is very much the theme of this musical but so is place, in the sense of where you belong. And, while Cornwall is in the DNA of this show, love is at its centre. Even so, his love story is tentative with many moments in which he retreats, thanks to his lack of confidence.

Elowen is the caring woman who becomes the love of his life. Played by Clare Foster, she exudes warmth. His two children are played by the excellent Anna Fordham and Oonagh Cox.  He has travels and adventures, which take place against the background of major events in the 20th century, particularly the Second World War and the race to the moon.

Along the way, he meets interesting and funny people such as Little Jack, played by Jack Quaron, another person treated with contempt because he is different. In this case, it’s because he appears to be of low intelligence, yet heturns out to possess natural wisdom. But Benjamin’s winding path always leads back to Elowen, where he belongs despite their widening age gap.

It is fascinating to see someone living his life backwards but, while we live our lives from childhood to old age, we are an accumulation of memories that, at any given moment, can take us to any part of our life, so we don’t exactly go forward. And Benjamin’s own experience is very similar to any person who is different, an outcast who needs to find somewhere he belongs, and who eventually fades. Time, which the chorus measures precisely to the second, turns out to be very flexible.

Unlike me, you may find the story too fantastical, too full of coincidences or just a bit thin, but you will love the music, written and arranged by Darren Clark. It has the overall effect of a folk concert in a Cornish pub, underpinning a joyous and moving evening.
