"I think I can run on another six years, which would take me up to 50 years, then [I'll] see what happens after that," the festival's founder said on Sunday morning.
However, he said the festival's "still got a few years in it", and spoke of the love those attending the event feel for it. "Every single person there last night wanted to shake my hand and say it's the best thing in their life. It really is quite phenomenal that appreciation of the event – 44 years and people love it more than ever."
Eavis said Glastonbury would be taking its next fallow year in 2017, and declined to name which acts he had already booked for next year's festival – despite saying all three headliners were already sorted. He said he had signed one non-British band while talking to their agent during Saturday night's Metallica headline set and admitted, "We're always having a go at Prince". He added: "Most of the people in the world want to play here, so I did ask him to hop on the train and come down to Castle Cary station and I'll show him around the farm some time. It hasn't been taken up yet though."
Eavis paid tribute to Metallica, whose set turned out to be something of a triumph, despite pre-festival speculation their set would fall flat. "I thought they were very good," he said. "The great thing about then is the generosity of appreciation of the show. We've never seen a band so keen on coming before, they're fantastic people."
He revealed that he had first spoken to the thrash metal titans about appearing at Glastonbury decades ago. "I promised them the chance to come about 20 years agom, and so the time was now. We could give them the slot this time for the first time. I think they filled it very, very well. Extremely well. So I think we're lucky to have them actually."
Eavis also had words about the cessation of live performance during the storm on Friday night: "Too many health and safety these days. We wouldn't have stopped it years ago, would we? I don't know whether we should have stopped it or not. It was a shame, but it was only for an hour."
