On the night before the night before Christmas, something is astir in The Camden Head. If it smells funny and sounds funny, odds are it's gonna be funny. Join a handful of London's top wits for a warming stew of improv comedy. The informal jam will be crowned with a special set from comedy duo Anne and Frank. Take your fill and savour every last morsel. Over 18s only. Valid ID may be required. Please note that acts are subject to change without notice.
