Tough Crowd is a great title for a show, but you know it's going to be a long hour when the first gag of the night is an attempted cheeky chuckle at date rape. Jason Kavan is a nice man with nice teeth, and we want him to be funny. But he's not and sadly this isn't a show; it's clunky, awkward, embarrassingly cobbled-together material, which feels like he's just jotted down a few bad gags on the back of a fag packet on the way to the venue. In between the empty silences when there eventually are gags, the punchline is pretty much coming over the hill waving.

It is all rather like watching the bloke at work who is under the sad delusion that he's hilarious. Unstructured, unfunny, opinionated ramblings, not so much making your toes curl but your legs bend. I've never wanted a fire alarm to go off so much in my life.
