Uncaged Monkeys: Night of 200 Billion Stars made me laugh, brought a lump to my throat, boggled my mind – but mostly it gave me hope in humanity. At least two of the main acts seemed surprised at the show’s success (“I can’t believe I’m standing in a medium-sized rock venue talking about physics”)  and the geekish excitement was palpable both on and offstage.

So what is Uncaged Monkeys? It began life two years ago as a touring version of Robin Ince’s Radio 4 show, The Infinite Monkey Cage.  The three-hour show - a cross between a series of short science lectures and a stand up comedy gig -  has sold out venues all over the country. I was lucky enough to catch the last night of the tour, in Brighton.
