Surrounded by a string of lights on the floor, two performers with white painted faces and the red mouths and black eye details of clowns take turns reading out to one another a list of questions in this durational piece. ‘Would you like to stop?’ is the key to this game, to which an answer of ‘Yes’ means that the questionee becomes the questioner.

This format is surprisingly and effectively watchable. At first you wonder if there is a rule about answering honestly as Terry O’Connor seems to be doing her best to answer each question to the best of her ability, but then you realise that each person has their own style, both in asking questions and answering them. There is a big ream of dog-eared A4 sheets of paper each with dozens of questions. After a couple of hours of Cathy Naden and Terry O’Connor, Richard Lowdon comes in with some beers to relieve Terry.

Cathy Naden is eminently watchable on stage, bringing an assured poise to her performance, relaxed yet with a remarkable attention to the moment and an assured stagecraft. Terry O’Connor, in contrast, seems vulnerable, a little crumpled, and Cathy plays with this like a cat plays with a mouse, alternatively indulgent and then honing in on Terry’s instinct for honesty. Asking ‘What do you really want?’ repeatedly, waiting for the answer Terry seems to be seeking to avoid. There’s a turn toward interrogation that runs as an intriguing undercurrent though the format. All the performers use the printed questions as only a loose prompt for further improvised questionings, and when the questioner occasionally strays into statement it is only for a moment as the structure of asker/answerer is what makes this durational piece what it is. When O’Connor is replaced with Lowdon the energy of the piece shifts and becomes harsher, more competitive. The energies are subtly shifted and Richard’s questions sometimes seem accusations to which Cathy responds with assured humour and aplomb. Longer imaginative connected questioning occurs and there is a hilarious riff about a cheap package holiday in Hell. Quizoola! is an inspired format – a kind of Christmas party game turned into a durational performance – but what makes it work and watchable is the quality of the performers.
