We still don't know which artists will be performing at next year's Glastonbury Festival, but we can be sure of this much: Plenty of people will be on hand to watch them play.

The NME reports that 25 minutes after going on sale Oct. 5, all 135,000 tickets to Glastonbury 2015 had been sold, proof that even without a list of headliners, people are more than willing to shell out for the privilege of standing in the mud with thousands of other rocks fans. "We're humbled by the incredible numbers of people who would like to come to the Festival -- and it's clear that demand once again outstripped supply this year," organizers posted on the festival's website. "We're sorry that some of you have missed out, but there will be a resale of returned tickets in the spring (and your registration remains valid for future years). Thank you all for your never-ending support for our Festival."

"We have sold out, thank you to everyone for supporting us," added organizer Emily Eavis via Twitter. "I’m sorry to those of you who have missed out."

As previously reported, U.K. oddsmakers have named AC/DC and Fleetwood Mac as two of the most likely headliner acts when the festival convenes between June 24-28 next year -- although the NME's report on the Glastonbury sellout notes that Queen have also emerged as a possibility. No matter what, it seems like those passes will be well worth the purchase price.
