Glastonbury 2015: AC/DC strongly rumoured (by us) to headline next year’s festival

The promoter is thought to have signed the Australian band as he watched Metallica take to the stage on Saturday

Michael Eavis has confirmed that he’s already booked the three acts who will headline Glastonbury in 2015.

The festival organiser teased who he’s signed to take to the Pyramid Stage next year, admitting he sealed one deal as he watched revellers (including closet fan Bradley Cooper) headbang their way through Metallica’s set on Saturday (28 June).

Fans Accuse Dolly Parton Of Miming

Speaking at the annual press conference, held on the festival site 11am on Sunday (29 June), he said: "We've got three headliners already – and that's without Prince.

"We've got some good headliners," he continued. "We had an agent [for a band] yesterday on the platform by the stage watching Metallica with me, saying 'My band want to do it next year'. I can't tell you who it was but that was done on the platform watching Metallica."

He went on to infer who the band in question were by tossing the waiting press this tit-bit to chew over: "Is it a British artist? He's definitely British, but the band are not British anymore."

For the record, our money’s on AC/DC, who comprise of British singer Bryan Johnson, brothers Malcolm and Angus Young, who were born in Scotland and emigrated to Australia when they were children, and Australian drummer Phil Rudd. Completing the line-up, however, is another Brit, bassist Cliff Williams, who was born in Romford, Essex, and has been playing with the band since 1977. But perhaps Eavis hadn't noted this fact.

The Australian-based rock band also share a manager with Metallica, Peter Mensch, who Eavis was apparently standing next to as they performed:

Peter Mensch is, of course, also the husband of former Conservative MP and heavy metal fan Louise Mensch.

The festival organisers are yet to confirm or deny whether our predictions are accurate.

On the topic of Prince, who was strongly to be among the secret acts performing at Worthy Farm this year, he said: "We're always having a go at Prince, but it's up to him whether he wants to do it or not. Most of the people in the world want him to play here. I did ask him to hop on the train and come down so I can show him around the farm sometime. It hasn't been taken up yet."

He also revealed that he was set to present legendary country singer/songwriter Dolly Parton with a prize for album sales.

"I'm presenting her with a record company award for the most number of records sold by a country singer at 2pm," he added.

"It's a lovely gold-coloured disc – I'm not sure if it's solid gold or not – because she's sold more than anyone else, apparently. I'll say a few words to her about her wonderful life and everything. I'm really looking forward to hearing some of those songs live for the first time in my life. Every one's a winner, isn't it."
