David O’Doherty’s unexpected if.comedy award at this year’s Edinburgh Festival delighted his modest yet fanatical following. Now, with this win under his belt a wider audience is appreciating the appeal of this shaggy-haired Irishman’s understated mission to “rock your world in quite a gentle way.”

This show has been supersized since its summer premiere, with extra jokes, extra songs on cheap Yamaha keyboards and extra whimsy. It is still as slick as John Sergeant’s tango but all the more charming for it. O’Doherty is distracted by fans, digresses and, at one point, rolls around the floor. This is not punchline comedy, more personality comedy. The 32-year-old manchild milks his infectious idiosyncratic worldview for every drop, imagining how it would be wonderful to see a performance of Cats dressed as a mouse and how Argos resembles an exotic mix of shop and bookies, with its tiny pens and paper notelets.

He proves that there are no hack subjects, just hack comedians. Even tackling much-trampled topics such as the internet or texting he sounds fresh. And his daft humour dovetails perfectly into his plinky-plonk songs. One lo-fi gem compares him to Tiger Woods. It is obvious who makes more money, it is less clear who is having more fun.
