Sketch comedy tends not to get the same love that standup does…but it's now time to recognise its brilliance. Python much? Each Sketchfest show brings you four of the very best acts competing before an expert comedy panel, including critics from The Independent, The Times, and more. The theme for this year is a comedy lab, representing all that is playful and imaginative in the sketch world. Tonight's rib-ticklers: Heffernan & Fletcher, Charles Booth, The Awkward Silence, and In Cahoots. General admission. Over 16s only. Please note that acts are subject to change without notice.
