Bono of U2 performs in the rain on the Pyramid stage during the Glastonbury festival near Glastonbury, Somerset on June 24, 2011. Veteran Irish band U2 headlined the Glastonbury festival, the world-famous celebration of arts and music which got into full swing today. 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.
