THESE incredible black-and-white photos show Britain's best-known festival as you've never seen it before.
As thousands of revellers start descending on Somerset for this year's Glastonbury we take a look back through the archives when the crowds were thinner - but the mud just as thick.

This shot, taken in 1971, shows the first time the Pyramid stage was used. Back in 1971, the festival was known as Glastonbury Fair, and was a far cry from the jam-packed festival we know today Credit: Getty Images 25
By 1982, when this shot was taken, Glasto had already morphed into something special. The festival was founded by Michael Eavis, who owns the land where it is held Credit: Rex Features 25
Glasto is well known for being a complete mud-bath. This shot of a man crashed out in a muddy mess, snapped in 1982, proves the festival has always been a muddy affair Credit: Rex Features 25
A muddy reveller can be seen bathing in the sun in this shot from 1992. Tom Jones was a surprise guest at the festival that year, which attracted 70,000 attendees 25

Glasto has never shied away from its hippy roots. This shot was taken in 1994, the first year when a wind turbine was used to power some of the main stage area Credit: Rex Features Britain's most famous festival takes place over five days at Worthy Farm in Pilton, Somerset.
The festival is named after the quirky town of Glastonbury, which is the closest big settlement and 20 minutes’ drive from the farm itself.
As locals will tell you, the festival has evolved drastically from its humble beginnings - although the mud is a permanent fixture.

In its first year, Glasto was known as Pilton Pop Folk & Blues Festival, morphing into Glastonbury Fair one year later.
But what started out as a small hippy gathering evolved into a revered event which now attracts over 175,000 revellers every year.

A shot from 1985 shows a pair of boots left behind in the famous Glasto mud. By this time, Worthy Farm was too small for the number of attendees, so nearby farmland was bought to expand the grounds Credit: Rex Features 25
A snap from 1989 shows a group of friends chatting and smoking on the bonnet of a car. Complications over festival licencing with the local council led to the police being brought in to organise and plan the festivities Credit: Getty Images 25

Glastonbury's first ever death occurred as a result of a drug overdose that year Credit: Rex Features Michael Eavis was inspired to use his farmland to host a festival after watching Led Zeppelin perform at the Bath Festival of Blues.
Now 81, the festival founder and lefty activist co-organises Glasto with help from his youngest daughter, Emily Eavis.
These days, 38-year-old Emily books the acts for all main stages, and may one day end up in charge of the entire festival.

With 2018 scheduled to be a Glastonbury gap year, founder Michael wanted to relocate the festival rather than cancel it entirely.
But next year’s festival was sensationally axed after he failed to find a host willing to use their land for the event.

Attendees experience VR for the first time, in a shot from 1993. 80,000 people descended on Somerset for the festival that year Credit: Rex Features Michael now wants to protect the site by moving the festival away from Pilton in 2019 as well.
He hopes that the second site he’s found will serve as a backup location where the festivities can be held once every five years.
The new site is “towards the Midlands”, according to Michael – and could be over 100 miles away from Worthy Farm.
