LONDON, 20 Dec 2014. This musical edition of mental wellbeing charity CoolTan Arts’ monthly walk will take you on a lively journey through Bermondsey as you learn about the musicians (both past and present) with connections to the area and the ancient Christmas tradition of wassailing. There’ll also be a few carols and festive songs thrown in for fun. The full route is about 4.8 miles, but participants are welcome to join for as much or as little of it as they fancy. Meet outside the Turbine Hall entrance of the Tate Modern at 11.45am.
