The memory can play tricks on you. Or have I said that already?” Ben Moor is obsessed with the past and future. In his latest intriguing monologue, Not Everything Is Significant, he unites his fixations, playing a blocked writer who finds his diary for next year spookily completed.

As well as being one of the bendiest, most balletic comedians around, Moor, a self-confessed “detail devil”, is exceptionally skilled at creating word-pictures of his upside-down world. Terrorists here are “birth bombers”, producing life, not extinguishing it. He describes a relationship by borrowing game-show host Roy Walker’s: “It’s good, but it’s not right.”

Moor glides around the stage, charting his unfolding autobiography. Invited out to an Essex car park expecting to see dogging, he sees people manicuring each other — “poodling”. Pubs are named after books by JG Ballard.

The non-crude comedy faction seems to be hooked on remembrance at the moment, with recent pieces by Daniel Kitson and Josie Long similarly playing with the way that the past exists in the present. If you appreciate their sensitive brand of personal whimsy, Moor’s haunting piece, which also echoes the work of Stephen Poliakoff, will stick in the mind, too.
