GLASTONBURY, ENGLAND - JUNE 26:  A tent in the shape of a London Underground Northern Line carriage is pitched precariously on a hill at the Glastonbury Festival at Worthy Farm in Pilton on June 26, 2014 in Glastonbury, England. Tickets to the event, which is now in its 44th year, sold out in minutes even before any of the headline acts had been confirmed. The festival, which started in 1970 when several hundred hippies paid £1, now attracts more than 175,000 people.  (Photo by Jim Dyson/Getty Images)
