You could say that Jonny Sweet is probably quite a lucky geezer. Born with a face (agile) and voice (rich) that could only have led him onto one possible career path, he is utilising those assets to maximum effect in this, his debut solo Fringe show. Having larked about with Inbetweeners stars Joe Thomas and Simon Bird in sketch lunacy The House of Windsor and site-specific silliness The Meeting and currently starring in Tom Basden’s excellent Party at the Assembly Rooms, it was always curious to see how he would fare up there on his tod.

Well, no one should have had any fears for him as Mostly About Arthur is a rollicking ride from the first moment he says the word ‘blurbist’ to the gloriously awkward musical finale. Arthur is our narrator’s deceased brother, a man who made his living writing descriptions on the back of books such as Guantanamo Gay and Furtive Fork, but whose career went down the pan when he wrote a blurb for a book he hadn’t even read, invoking the wrath of the major blurb critic. With the aid of splendidly pitched PowerPoint, Sweet tracks Arthur’s beginnings in Filey through to his ultimate demise, the details of which are best kept secret.

Wielding some enterprising audience participation and never making a wrong move with the script or its delivery, Sweet keeps the laughs rolling as the bitter, awful conclusion looms. With the confirmation that he will play the young David Cameron in a More4 drama documentary, it could well be that Sweet will soon leave all this Fringe nonsense behind him. That would be a crying shame.
