Tickets for this year's Glastonbury Festival have gone on sale, with organisers promising extra measures to prevent tickets being bought by touts.
Mr Eavis wants to discourage touts
The festival, which takes place from 25-27 June, will this year be headlined by Oasis, Sir Paul McCartney and Muse.
Founder Michael Eavis has stopped festival-goers from buying tickets by credit card, and they will be limited to two tickets per booking.
Tickets went on sale at 2000 BST. Last year they sold out in 23 hours.
The 8pm start was an attempt to dissuade touts and allow people who are at school or at work to buy tickets.
Tickets will have to be bought by debit card, because organisers thought touts had bought multiple tickets by credit card last year.
Every tickets will carry the name of the person who bought it. Identity checks may be carried out at the festival gates to ensure people have not bought their tickets from touts.
In the last few years Mr Eavis - who has run the event since its inception in 1970 - has invested more and more money into preventing gate-crashers and drug dealers entering the site.
In 2002 Mr Eavis invested more than £2m in new fencing designed to keep out people who had not bought tickets.
Last year he pleaded for people to stay at home if they did not have tickets.
