Glastonbury boss Michael Eavis has said he is "sure" that Led Zeppelin will reform in the future, NME reports.
The classic rock band have long resisted offers to reform and play together again, and their last proper show was at London's O2 Arena in December 2007, where they were joined by Jason Bonham, son of the band's late John Bonham, on drums.
However, in an interview with Ireland AM, Eavis said he was convinced they would share a stage once more and that he had always wanted them to play at Worthy Farm. Asked if the group would ever reform, he replied: "That will happen one day – I'm sure of it. They will do it."
He also made a cryptic comment about a band who he would never invite back to play the festival again, but only referred to them as a band from Manchester "who aren't famous any more ... they fell out".
The team behind Glastonbury festival have confirmed they will release the full line-up for the event later this month. Already confirmed for the festival are Lana Del Rey, Arcade Fire, Dolly Parton, Lily Allen, Disclosure, Blondie, the Black Keys and Warpaint.
Arcade Fire are the only confirmed headliners for this year's festival, and will play on Friday June 27. William Hill suspended betting in February on Kasabian headlining the Pyramid Stage, while on March 27 Paddy Power made Metallica and Prince joint favourites to headline the Saturday of the festival. However, Emily Eavis recently said that Prince "wasn't booked this year."
Glastonbury Festival takes place from June 25-29 at Worthy Farm in Pilton, Somerset.
