"My new show deals with inter-governmental crises in Corsica between 1986 and 1987," says Irish comic Dylan Moran.

"Then, after the interval, I demonstrate the pitfalls of gargling ground glass in a wind tunnel. There's a good deal of strobe lighting throughout, hence the popularity of the show with the over-85s."

Blatantly untrue, this nonetheless gives a sense of what Moran's show will be like, though why he wants to do the show at all is less clear.

With two successful TV Sitcoms under his belt, How Do You Want Me? and Black Books, and a film role coming soon opposite Michael Caine in The Actors, one can't help wondering why Moran has chosen to put himself through the ordeal of two hours in front of a live audience.

"Being on screen is all very well," drawls Moran. "But there's nothing like roaring into a strangers face to make you feel alive."

Live, there's an edge to Dylan Moran's show which comes from its unpredictability.

As he wanders distractedly around the stage, accompanied by a packet of cigarettes and several bottles of wine (which disappear at an alarming rate) musing on anything from modern technology to global diplomacy, he veers off on seemingly unconnected tangents, before returning to the point - or not.

He has even been known to take a little lie down on stage, leaving the audience wondering if he's ever going to get up again. Whether deliberate or genuine, this constant change in tempo gives a rollercoaster ride.

At one moment you're laughing until your sides split, the next sitting nervously on the edge of your seat as Moran teeters at the edge of the stage, inexplicably at a loss for words.

Very funny in an unquantifiable way but is he trying to make any social point with his jibes at the way we are? "No," he says, "I'm absolutely not."
