The last London show of 2012 was the biggest of the year, with a packed bill of magic, stunts, dance music and comedy. Headlined by the mighty Mr B The Gentleman Rhymer, and in conversation, the delightful Arthur Smith, who amongst other things, advised not to go to the Edinburgh Fringe, confessed he had nothing against jugglers and sang Jingle Bells. Backwards. What's not to like?
