Stand-up and prankster Dave Gorman is at his best when he's set himself a task, a job, a target. He's (in)famous for his adventure, that found him traversing the globe to find the authors of the ‘googlewhacks’, (internet search engine queries that only return one result), and his book (and stand up show) Are You Dave Gorman?, in which he sets out to find others around the world who share his name.

His new show, Sit Down Pedal Pedal Stop and Stand Up, started life as an environmentally-friendly stand-up tour where the gimmick was to carry out a Lands End to John O’ Groats style bike journey, performing stand-up comedy as a break in the evening. Its popularity proved so high, he has continued touring with the show’s name and dropped the gimmick (for the sake of his feet, family and sanity).

However, what ensues is a show which is a little strained. Perhaps this is because Gorman lacks the concrete subject matter of previous excursions and adventures (there is barely a mention of his biking challenge, for one). In a later routine,he describes, in great detail, a prank he brazenly admits he only set up to gain material for the show. The skit is painfully extended; its inclusion is merely as filler.

Gorman clearly has stand-up ability; he didn't gain his cult status just for his high concepts. He's an affable performer, and his comedy is largely gentle and charming. The highlights of the show are when he indulges in ‘geeky’, jarring, banality (his routine about perfect, friendly and sociable numbers) and digresses on minutiae (a later routine involves the origins of a popular cereal).

Yet, there's an undercurrent of sadness that permeates, and sours. Somewhat tragically, he recognises he’s at a time in his life (he's 38) where his practical jokes are now less satisfying. Unfortunately, from much of the evidence presented, this mellowing and self-realisation may not be good for long-term prospects as a stand-up comedian.
