Just like his previous shows, Reasons to Be Cheerful and Better World, Dave Gorman's latest vehicle is a brilliant example of what can happen when you take an idea and run with it. The idea is this: Gorman set out to find, meet and photograph himself meeting other Dave Gormans. A simple enough notion, maybe, but it inspired one of the funniest shows in years - an hour-long rollercoaster of comedy.

Gorman first goes to Scotland, where he meets the assistant manager of East Fife Football Club, Dave Gorman; then he goes right round the world. There's even a Dave Gorman in this audience. We share Gorman's excitement as he locates his first gay namesake, and his heartbreak as he is cruelly refused a meeting with Dave Gorman of Leamington Spa. By the end of the show, he is offering £300 to anyone who will change their name by deed poll, and a desperate, entire grand to the person who will christen their child Dave Gorman.

The tale is fascinating and Gorman's immaculate timing and deadpan delivery mean there is scarcely a second's break in the hilarity.
