We Are Klang In Yee-Haa Klang, The Pleasance, Edinburgh

The nice thing about this sketch show is that you get the feeling that its three protagonists could keep coming up with sketches all night. What was delivered by the troupe wasn't always of curtain-raising quality, but when it was, it induced good, healthy belly laughs.

The Klang trio is formed of three relative newcomers: the tall, imposing Greg Davies, who is 70 per cent Rik Mayall and 30 per cent the comedy actor Peter Serafinowicz; Marek Larwood, a smaller version of Matt Lucas and similarly ghoulish; and the urbane Steve Hall, who played most of the straight characters.

Their best moments come when they are at their most un-PC; eg, acting out a game of one-upmanship between two grunting tramps and their cardboard signs. They even try to undercut their bid for tea: "50p for a cup of tea" reads one, "20p for a cup of weak tea" reads another. At the end of the show there is a rousing song urging us to lay waste to the planet because the children that will inherit it are "scum" - so it's funny as well as being broadly accurate.

In between, there are skits of varied efficacy: a rogue estate agent and a naff Derren Brown figure are ragged, while a more naive piece around the mistranslation of a French Fringe play (where the phrase "Qui s'appelle la pere?" is relayed as "quiche apple, pear") has undeniable charm.
