Crizards Will Rowland and Eddy Hare say they've been called the "UK's lowest energy double act" and that is certainly not a case of mis-selling. Their new show Cowboys is so laid back it almost collapses in on itself. The duo play cowboys and spend the hour singing songs, telling stories about their cowboy life and having a little adventure..

It's an odd, amiable show but not in the way I expected. For the Wild West this is not really very wild. It is directed by Jordan Brookes so in advance I was imagining more of a Brookes-style skewed sensibility, but by and large this is played as pretty straight double act comedy, with echoes of dopey Stan Laurel and anxious Oliver Hardy on the trail of the Lonesome Pine.

The loose plot is about them setting out on a rootin' tootin' journey across the prairies so that Will can blow up a railroad in an act of revenge. It could have done with more dynamite for me. There's a bit of gentle prop-work involving some fake quicksand (played by a sand-coloured sheet), which we are told is “twice the speed of normal sand”, but the meat of the performance is the interplay and the songs.

And the songs certainly do hold their own, catchy and infectious, even if they are also pretty chilled out. At their best there is a whiff of Flight of the Conchords, while the conceptual nature of the show has a touch of early Mighty Boosh about it. 

Along the way they get philosophical and talk to the moon, fall out and fall back together again and reveal a sentimental back story that explains a bit more about what is going on. It's a mix of yee-ha and ha ha. 

The problem is the energy crisis. I just wish that maybe they could up their levels a bit. But then, of course, they'd lose their unique selling point of being the UK's lowest energy double act. A cult act in the making even if their saddles aren't so much blazing as simmering gently.
