The night begins innocently enough, with a lovely song about an office crush that veers into the corporate mistreatment of camels. The audience are instantly on board with Jonno, needy only child and head writer for Saturday Night Live UK, who stands alone on stage with his banjo, seemingly jittery in his debut stand-up hour despite having made a Fringe name for himself as one third of sketch gang Sheeps. However green he appears, Jonno is clearly very comfortable fiddling with the format, repeatedly misdirecting the crowd and gleefully swerving until everyone’s a bit dizzy.

There’s an impression (well, he makes it clear) that this is all for his own entertainment. His funniest material is perhaps the most straightforward: not being on the telly, for example, and the increasingly desperate routes he might take to get there (hello, disastrous improvised rap). There’s also his five greatest fears: some understandable (goblins), others downright bonkers (clothes), and a very committed Bond medley. Beneath all the misdirection, the show is about moving from behind the scenes into stand-up, while touching on anxiety, self-sabotage and avoidant attachment. His nervous energy and vulnerability create a likeable, slightly frazzled persona. But he’s not completely alone: tech Jake does more than just operate the lights and sound, and his little cameos reveal just how carefully constructed the apparent chaos really is. This is an inventive, enjoyable hour, even with all the twists and turns.

Jonno: Here Comes Mr Funny, Monkey Barrel, until 30 August, 7.10pm.
