Dermot Whelan has youth and charisma on his side, and so makes for an engaging, cheery presence. But his material slips too easily along such formulaic lines, that you instantly know how each routine will pan out.

Imagining a more realistic Thomas The Tank Engine, for example, prompts predictable scenarios about delays and incomprehensible announcements that every commuter complains about. And what’s the deal with Teletubbies? They must have been stoned to come up with that idea! Yes, it’s the most obvious line – and he’s still doing it.

So when he brings out his guitar, it comes as no surprise that he just changes a few words of hit songs to make them about something else.

He gets away with his bad writing habits a bit more when talking about news stories, as the topicality gives him some extra latitude, but it’s generally a shame a comic with such nice air about him, has put so little thought into the gags.
