The moment Liam Farrelly steps on stage, it’s obvious that he’s from Glasgow. His repertoire is thoroughly Glasgow-centric with all the observations and jibes about the city we’ve come to expect: nobody eats fruit and everyone’s got rickets. The material might be fairly straightforward (think the Catholic church is full of paedophiles and a bit of good-natured sectarianism) but the pure speed and slickness with which Farrelly delivers the show makes is seem as though he’s been honing the craft for decades. Except that’s impossible: he’s only 21.

No sentence is wasted and each arc comes with a solid right hook of a punchline. Callbacks to his mad mate Sharkey are particularly welcome. There’s no time for a lull or a moment without someone laughing somewhere in the room and he chucks out swear words like they’re sweets. The ending, featuring complaints from a religious American man about the show itself, feels a little tacked on, but that’s probably because he only added it during the Fringe’s first week. 

Just The Tonic Nucleus, until 28 August, 7.10pm.
