Lead singer of Coldplay Chris Martin performs on the Pyramid Stage at the Glastonbury festival near Glastonbury, Somerset on June 25, 2011. This year’s festival features headline acts U2, Coldplay and Beyonce. Now in its fifth decade, the event has grown from a humble gathering of 1,500 people on Michael Eavis’s Worthy dairy farm in 1970, each paying one pound and receiving free milk, to a giant five-day celebration of music costing 195 pounds for a basic ticket.
