Organizers of the U.K.'s Glastonbury festival have confirmed that tickets for the 2010 event will go on sale at 9am on Oct. 4.

The festival will run June 23-27. The line-up is traditionally announced nearer the time after tickets have sold out.

This year also marks 40 years since the first Glastonbury festival at Worthy Farm in Somerset.

"The Festival's long awaited 40th anniversary celebrations start here," said founder and organizer Michael Eavis in a statement.

Eavis has previously said the festival will draw on performers from throughout its history for 2010.

"Now I'm fully confident that the anniversary line-up will be just that little bit special when it is revealed next year," he added. "We want as many people as possible to be part of the celebrations and to enjoy what we do here."

Ticket sales are via and through a dedicated phone line. An international sales line can be found on the official Glastonbury Festival Web site, along with full information on the registration and ticketing process. Registration including photo ID - a measure launched in 2007 to prevent scalping - must be completed by Oct. 2.

Tickets cost £185 ($306) plus booking fee and delivery. Customers will have the option of buying a full ticket up front or paying a deposit of £50 ($83) to reserve a ticket, with the full balance due by Feb. 28. The deposit scheme was introduced last year.

Eavis added: "We have the fairest ticketing operation available anywhere. With this scheme, backed by the all-important registration process, everyone has an equal chance of getting a ticket. And most importantly, every ticket will only be going to a genuine festival-goer direct."
