In this hotly anticipated Fringe debut from the talented Glaswegian comedian, Jack Traynor tells of how his grandad (the ‘big man’ who brought him up) has been reduced by dementia and is living in a nursing home. It sets the comic off wondering what he will forget when he ‘inevitably’ gets dementia himself. Traynor is a hugely charismatic performer and certainly knows how to pen a gag, shooting out finely tuned punchlines throughout. He’s masterfully quick to respond to folk in the audience too.

The only quibble is that it feels as though he’s not fully committed to his theme. He openly jokes about shoe-horning it in because that’s what’s expected from an Edinburgh show, resulting in an enjoyably silly running visual gag to distract us from its supposed lack. But conversely this gambit sets up the expectation of a more structured show, which he doesn’t quite deliver on. Perhaps he’ll develop more faith in his own theme as the run goes on. Regardless this is a debut that certainly showcases his talents as a stand-up and it’s very clear he’ll go far.
