Dust off your Santa hats, sparkly antlers and elf ears, and join London City Voices rocking around the Troxy Christmas tree. Have yourself a merry little Christmas, with lots of seasonal favourites and a few lesser-known melodies. Led in inimitable fashion by Richard and Ben Swan, London’s friendliest choir present a sparkling evening of festive delights – followed as ever by the best party south of the Watford Gap.
