Actions count, not words, insists Alfie Brown with his latest provocative Fringe hour. A shame, then, that he is so good with language and imagery, but thankfully he is able to get those words into the public realm by taking total command of his stage. Brown's style remains a potent mix of cheeky scamp and verbose preacher as he rails against the kind of 'performative dads' he meets in the park while acknowledging his own parental failings. A 'horrible honesty', he proposes, is way better than those pious soundbites we all make in order to be on the right side of the debate.

And a large bulk of Lunatic has him laying out plenty horrible stuff. The heart of his hour revolves around a man who collapsed nearby while Brown was impatiently waiting for a bus to get him to a gig he was already running late for. He may have stood inert while others around him exploded into action, but is this unfolding drama the kind of sight he needs to witness to put his own troubles into some sort of perspective?

This is just another bold hour of stand-up from Alfie Brown which dares to delve into the darkness and consider what it is that makes us human.
