Jay Lafferty is often heard compèring for other comedy acts around the UK, so opening banter with the audience is comfortable territory for her. It’s the usual “where is everyone from?” patter upon arrival, but Lafferty is warm and welcoming and makes us laugh without resorting to berating anyone.

After the warm-up, she delves into the show’s underlying focus – the idea of luck, via an explanation (needed for the out-of-towners) that this is essentially what the Scots term ‘jammy’ (the show‘s title) means. We’re given childhood anecdotes and exaggerated examples of jamminess, before we transition to the main act of the show – framed around a luck-themed questionnaire the comic sent to 300 people. Each question signposts a new segment: differences in cultural approaches to the idea of luck; the relativity in perception of luck; and various hilarious examples of questionnaire answers about ‘the luckiest day of your life’. Of course, the comic hand-picks the funniest selection of answers, adding in her own quips and witty observations.

Lafferty is quick, reactive, and masterful at creating a communal atmosphere in the hot Turret room of the Gilded Balloon Teviot. As is standard with many stand up sets, we build to a more personal finale as Lafferty draws us in with a story about her pregnancy. It’s difficult to be cynical or worry that this is a contrivance, though. We sense the comic’s genuine register and are left with a feeling that this was no ordinary show for her to write.

Jammy is a buoyant showcase for a performer who is utterly comfortable on stage and skilled with an Edinburgh audience. We are never disengaged and the crowd leaves still chuckling and revelling in Lafferty’s levity and sincerity.
