Villagers fear the reaction of gatecrashers

Avon and Somerset Police say they are aware of the potential problems.

But their biggest concern is to prevent the overcrowding which threatened safety in June 2000, when about 100,000 people got into the site without paying.

Police said it was "dangerously unsafe" and last year's event was cancelled.

Organiser Michael Eavis warned that if security fails this summer, it will be the end of the festival.

He has enlisted live music company, the Mean Fiddler, to take over operational control.

The 12-foot super-fence will stretch seven kilometres around the perimeter of Worthy Farm.

Security chief, Bill Stuart, is confident it will keep out gatecrashers.

"It's definitely going to do it, without a shadow of a doubt," he said.

"We're determined to keep people out.

"And the message is 'if you don't have a ticket, then please don't come'."
