This gargantuan pop-fest takes place on the first Sunday of July every year. It's the festival in London for catching several big name acts on one ticket. The event is sometimes a bit mud-ridden, although the atmosphere is blazing whether the sun joins in or not. The purpose of these gigantically high-profile open-air concerts is to raise money for the Prince's Trust, and usually to great effect. Tickets are usually in very high demand so make sure you get yours in advance. view all details
