Comedian Al Murray is seen in Allen's of Mayfair, London's oldest Butchers shop, as he launches 'British Sausage Week' in London today (05/11/12). As part of the week, running from the 5th to the 11th of November, butchers across the country are challenging customers to make them laugh with their best sausage jokes which will be judged either a 'banger or a clanger'.
