Henry Paker has one of those lovely minds that sends out little constructs of the gleefully absurd in all directions. This is a charming, friendly show where ad-libbed flights of fancy spiral out of observations and Paker ties himself in delightfully daft knots. If you like Bill Bailey but can’t bear the thought of what’s living in that hair, try this one.

The GRV, 226 0000, until 29 Aug, 7.50pm, £5.
