And so, to sleep – but what dreams may come? For Kenny Gray, who yawns his way onto the stage resplendent in blue pyjamas, the answer seems to be “eclectic and funny ones”. Kenny Goes To Sleep is at heart a one-man sketch show, warmly entertaining from beginning to end and delivered with loveable charm.

Most of the sketches are character studies, with an entertaining short story about their subject interleaved among the witty lines. From the high-school teacher with a competitive streak, to the hotel reception clerk who’s a little too concerned about his guests’ desires, each figure we meet has a touch of personality and enough vulnerability to make us care. There’s variety here, too: a thoroughly modern pastor adds a burst of energy, while another sketch brings us sultry seduction in hilariously improbable form.

Gray also has a few unexpected skills. I won’t spoil the surprises – but more than one sketch starts as a pastiche of a performance style, and then unfurls into something not just comic but genuinely impressive to see. The songs played between sketches are a subtle highlight too, each one carefully matched to the scene we’ve just enjoyed. These slight hints of vaudeville set the show apart from typical sketch-comedy fare, and mesh impeccably with the smart and speedy character-building.

But the one character we don’t really get to meet is Kenny himself. He sets things up by telling us he hasn’t slept well lately, and towards the end we get a hint of what’s been haunting his nightmares – but the idea that he’s dreaming all these scenes doesn’t go all that much further. The show doesn’t need a framing device to justify itself, but since it chooses to give us one, it’s a shame the wacky dreams don’t tell us a little more about the man who’s apparently dreaming them.

But this is, in the end, simply a lovely show – fresh, surprising, uplifting, made of equal parts laughter and charisma. A carefree fifty minutes that are well worth setting an alarm for.
