Glastonbury at 40

To celebrate the festival's 40th anniversary, the Community Channel sent a film crew to Glastonbury 2010 to find out more about the pioneering work of the many unsung heroes from numerous UK charities who go there every year to raise money. WaterAid, Oxfam, Greenpeace and many others have traditionally been part of the world's favourite music festival and this film talks to some of their hard-working volunteers to find out what it's like.
