Living proof that style often triumphs over content

Simpson's irresistible energy and evangelical delivery can engage the most jaded of rooms - which is even more of an achievement when you consider the sheer paucity of his material.

His topics seem stuck in a timewarp, covering such hoary chestnuts as the deep-voiced guy who does cinema ad voiceovers, and he does so with little insight or originality.

Though his infectious stage manner carries him a long way, it can't overcome the dreary lack of invention that lies where the soul of act should be.

There is the very occasional funny line, but it all seems like woefully inadequate papering over the gaping holes in his creativity.
