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. Tonight's guests are Maeve Higgins, Tiernan Douieb and the wonderfully rambling Gerry Howell.

They 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".
