Jason Byrne is one of the bravest comics on the circuit.

More than half his act was improvised on the strength of disclosures from the audience and the rest seemed barely more rehearsed.

As manic as Scooby Doo on Guinness, the flame-haired Dubliner relied on breakneck trains of thought to generate a flow of loosely-associated ideas.

When he ran into a dead end, he returned to a member of the audience and asked them another question of the "what do you do for a living?" variety.

Some of the results are priceless. He persuaded a policewoman in the front row to demonstrate his thesis that all women can make perfect towel turbans after washing their hair- something no man can do.

The policewoman was very reluctant - making her eventual effortless display all the more enjoyable.

Having proved Byrne's point, she hurled the towel back with splendid panache.
