Tickets for next year's Glastonbury Festival have sold out in a record one hour and 40 minutes.
Event organisers Michael Eavis and his daughter Emily said they were "genuinely humbled" by the sheer number of people who wanted to attend the 2013 event.
But, they insisted, demand had "simply outstripped supply". They posted on Twitter: "Tickets for Glastonbury 2013 have now sold out, in 1h 40m (a record)."
Millions of people tried to log onto the ticket website when it opened at 9am on Sunday, but many were unable to get onto the page because of the volume of hopeful music fans.
Eavis tweeted: "Sorry to everyone who missed out and for any problems you had with the booking site."
There will be a resale of any cancelled tickets, which cost £205, plus an £11 booking fee and postage, in April.
The line-up for next June's festival at Worthy Farm in Somerset has yet to be announced.
Beyonce was one of the main attractions in 2011, while the event took a break this year to "rest" the farmland, as it does every few years.
The festival started in 1970 when several hundred music fans paid £1 to watch Marc Bolan, but it now attracts more than 175,000 people over five days.
Glasto has kept building on its hippie and rock roots, now featuring world, electronic, reggae, folk, hip hop and dance music too.
