This looks like fun, from the London Theatre Guide

“Cast members from Monty Python’s Spamalot are hoping that the public supports them on St George’s Day (23 April) as they attempt to break the Guinness World Record for the world’s largest coconut orchestra. The current record stands at 1,789 and was set in March 2006, outside the Shubert Theater New York, to celebrate the first birthday of Spamalot’s Broadway production. This new record attempt will be held in Trafalgar Square, so has enough room to smash the current total.”

“Taking part in such a prestigious record attempt is not as easy as turning up and banging two halves of a tasty, healthy snack together. Aspiring record-breakers need to have registered at a Trafalgar Square checkpoint by 18:30 to be assured of their exclusive Monty Python coconut. They will then be taught how to play their husky instruments by members of the Spamalot team. The official record attempt takes place at 19:00 and is followed by an al fresco screening of Monty Python And The Holy Grail at 19:30. ”

If I’m in town, I’ll try to be there to record the event for posterity.
