It is, naturally, a much harder world that comedians may find themselves in at the Fringe compared to those more atoned to the theatre world. Plays do not change scripts on the size of the audience, whereas comedians immediately have to adapt to their new surroundings - upon seeing the meagre crowd assembled for this particular showing, Cassidy admitted it wouldn't take long to ask everyone where jobs everyone did.But part of the skill is to win over an audience whatever their size, and while Cassidy is a pleasant enough individual, his routine - based on offensive jokes that he wouldn't be allowed to perform at this year's Royal Variety Show, was only funny in fleeting moments, while other moments left you relieved that he wasn't actually going to be meeting her Maj et al later this year.Some moments of Cassidy's show were high in originality; for example his recreation of a That's Life moment from the 1980s where a dog said 'Sausages', and how this could propel anyone to worldwide fame was entertaining and well thought through. But other moments were recovering old ground somewhat - excuse any unintentional pun here, but this year's Fringe has done Raoul Moat's Facebook page to death, whereas last year's should have made for the end of most Josef Fritzel routines. The conclusion to the show, where Cassidy brings all his 'banned' ideas into one all-encompassing routine for use at the Royal Variety Show, is funny but under-developed; similarly his alter-ego 'Ron', standing for Racist Offensive Nonse, gets barely a couple of lines to fully show off his character. Plenty of effort here, but not quite enough forethought to totally engage an audience, of whatever size.
