Backed by Radio 1 DJ Jo Whiley, these exclusive unplugged gigs in one of London's nicest venues are the second such series for the UK's top learning disability charity Mencap. Tickets for Athlete, Keane and Snow Patrol have sold out already - but a new batch for Babyshambles, Kate Nash (left), The Kooks and others have just gone on sale. A rare chance to see big names play acoustic sets in intimate surroundings.
