“The 57th Edinburgh Fringe Festival, the world’s biggest arts event, is under way. Thousands lined the route as the traditional opening cavalcade snaked past the castle walls in an eruption of colour. The city’s streets filled with festival goers, performers, celebrities, tourists and the media as the spectacular procession got into full swing. This year’s three-week programme offers more than 1,500 shows across the spectrum of the performing arts.”
