The National Youth Theatre has today celebrated it's 50th anniversary. The free event took place in Trafalgar Square, in the form of a play with a musical side called "God Save the Teen" about the cultural force that teenagers and their rebellious behaviour have been throughout the decades, in the form of a story about a 1956 teenage boy who falls in love with a 2006 teenage girl by travelling through time due to "The Cliff Richard Effect". Young actors from all over Britain made the cast. The play would often "flood" into the audience and also invited the audience to participate. Here are some photos of the goings on. Enjoy.
