Meet the milkmen of Glastonbury
Revellers at the first ever Glastonbury in 1970 each got a free pint of milk. Nearly 50 years on, it's still delivered direct to people's tents - but it costs £1.20 a pint.
Much of the milk comes from the Eavis's own cows; and providing a link between the festival and Worthy Farm's real business.
Greg Newman has been volunteering on the milk float for 12 years. He took the BBC on one of his rounds.
