Hugh Butternut (musician), Buzz Maxwell (magician) and Bobby Bean (the one who thinks he's funny, but isn't) were all part of a would-be comedy trio who 25 years ago thought they had hit the big time when they won themselves a slot on a prime-time television programme. But things didn't go quite according to plan: the big break turned into a permanent career break for the trio, who, over two decades later, come together to relive the past - and some comedy routines that came out of the ark.
Triple Espresso is one of those American comedy theatre shows that clone themselves in cities across the US. Billed as "a highly caffeinated comedy", it offers a theatrical experience akin to visiting one of the big burger chains: you know you are going to get the same thing whether you are in San Diego or Chicago. Or, presumably, London. But something seems to have gone awry: I reckon we must have got the decaffeinated version. And I don't remember ordering double cheese. But that seems to come as standard, along with the ham.
This show is really just an excuse to rehash some old jokes, routines and toe-curling audience singalongs within a theatrical format. It is amiable enough, but rather than bridging the gap between comedy and theatre, it slips between the two. A theatre audience will bemoan the lack of character development or narrative tension (the so-called scandalous TV appearance wouldn't make your granny blush, and it involves a routine every English schoolboy knows). And a comedy audience will find the jokes too lame and inoffensive.
Just occasionally the show exhibits signs of life. I started to warm to Bill Arnold's deadpan failed magician, Buzz, largely because he seemed to have the emotional make-up of a serial killer and I was hopeful that he might eventually dispatch his irritating companions. There is also an unexpected and slightly bizarre interlude involving some rather clever shadow puppetry.
The show needs more surprises like that to make it witty and original. As it is, it is a very tired old blend, not a gold blend.
