The perma-lovely and perma-inventive Josie Long presents a night where new comics and other guests alert the world to obscure facts, unknown gems and unsung heroes.

Performers will present short lectures and sketches to inform the crowd of things they've uncovered, and people who may otherwise have been ignored by history. Sketches, mucking around and unexpected finds! Bring your own recommendations and facts too to enter them into the "register of obscurity".

For starters tonight, Josie et al will be publicly vindicating William Blake's ghost by recreating his lost masterpiece The Ancient Britons.
