As Glastonbury gets under way this weekend, we took a statistical snapshot of the UK's biggest and brightest music festival.
There have been 82 headline acts on the main stage, which took on its distinctive pyramid shape at the second festival in 1971. Van Morrison, Elvis Costello, The Cure and Coldplay hold the joint record for number of headline appearances with three each. Six main stage headline acts have pulled out - The Kinks (1970), Red Hot Chili Peppers (1993), The Stone Roses (1995) Stevie Winwood (1997), Kylie Minogue (2005) and U2 (2010).
Festival-goers at the first Glastonbury in 1970 enjoyed free entry and were given a free pint of milk on arrival.
The 1970 festival saw a modest gathering of 1,500 people, who witnessed a performance from T-Rex.
This grew to 12,000 in 1971, but the festival was not held again until 1978, when 500 held a small impromptu event.
From 1979, it became a three-day affair, and attendance increased year by year until passing the 100,000 mark in 1998.
During the 1980s and early 90s, Glastonbury attracted large numbers of new age travellers, but as the festival grew, its dynamic shifted. Free admissions ended, ticket prices rose steadily, and fences were made higher.
The festival is now considered the largest greenfield festival in the world. All 135,000 tickets for 2013 sold out in 1 hour 40 minutes.
