We last saw Marcus Brigstocke four years ago in the very same theatre when he was giving us his views on The Brig Society, a first rate comedy diatribe on David Cameron’s Britain. Now he’s back with a reflection on why the long face; in other words, why, given that he has a privileged existence, do so many things annoy or upset him. Rather like the Ancient Mariner – a sadder and a wiser man – Mr Brigstocke has gone through a few upheavals since we last saw him. Thus he digs into some of his personal recollections and confessions to excavate some painfully touching observations and create one of the most open and honest comedy shows (and funniest) I’ve ever seen. He really lays himself bare for our consideration and reaction – in fact, slightly barer than one might expect, come the end of the show.

The EU referendum is something of a gift for Mr Brigstocke. Not the result, far from it; but it gives him a raft of brilliant material which dominates the first half of the show. For staunch, moaning, metropolitan elite remainers like Mrs Chrisparkle and me, his wallowing in sheer rage and his deft destruction of Brexit’s immense stupidity was like therapy. At (very) long last, I felt empowered to laugh at the result and not merely be miserable or disgusted by it. It was like popping a champagne bottle of pent-up frustrations and letting it overflow out into the stalls. It has to be said: if you are a proud Brexiteer, you are going to hate this show. I really couldn’t recommend it to you, because you will feel attacked, humiliated, shamed and probably in a woeful minority. For those of us who take the opposite point of view, for one magical evening we were allowed to share in blissful mockery. It was heavenly.

There’s a lot of audience participation but none of it is scary. He achieves this in a number of ways, for example, ascertaining who the teenagers are and making sure they’re enjoying their lives – then identifying everyone else by their age, decade by decade, peaking at the 60+ bracket. A lot of his material bounces off the fact that he is a straight white male (all the SWMs have to cheer to identify themselves) but nevertheless he likes musical theatre (another cheer to prove that, yes, we do exist). He asks us to shout out our favourite stage musicals – Les Miserables, Rocky Horror and A Chorus Line (my contribution) proved to him that we were camper than we looked. He asks the audience how many of us are the happiest we’ve ever been – which creates some rewarding and funny responses; he discovers how many of us have been on a speed driving awareness course – so many! There’s a cringe-inducingly brilliant sequence where he describes being accosted by a non-empathetic Geordie, the reason why Ed Miliband lost the last election and his take on a girl’s reaction to her first period – which not many male comics would be able to get away with. So there’s a lot more than just post-Brexit angst to enjoy.

Mr Brigstocke was absolutely on fire last night. His rapport is instant, his confidence reassuring. He’s not afraid to speak his mind, but you sense he would be respectful in debate (not that anyone was disagreeing with him). He really lets you into his own private world and makes you welcome. His material is fresh, original and very funny. Two hours in his company was a tonic for the soul. (Does not apply if you are pro-Brexit!) His tour continues into December and I couldn’t recommend him more strongly!
