Glastonbury organiser Michael Eavis has issued the surviving members of Led Zeppelin an open invitation to headline his festival whenever they like, adding that he is "sure" that they'll reform at some point in the future.
Robert Plant, Jimmy Page and John Paul Jones have played just one gig since drummer John Bonham died in September 1980, a 2007 benefit concert in London's The O2 at a tribute concert for Ahmet Ertegun, the founder of Atlantic Records, where Bonham's son Jason replaced his father behind the kit.
Speaking to Ireland AM, Eavis said that he had long wanted Zeppelin to be the centrepiece of his festival and that it "will happen one day - I'm sure of it. They will do it."
He also took the time to comment about a band who would never be invited back to the festival, saying that they were a band from Manchester who "fell out" prompting theories that he was talking about Oasis - another band who've been tipped with reforming for Glastonbury one day.
This year's Glasto boasts a line-up of Arcade Fire, Lana Del Rey, Dolly Parton, Lily Allen, Disclosure, Blondie, The Black Keys and Warpaint.
Further headline acts are due to be announced over the coming weeks and months, with speculation suggesting that one or both of Metallica and Prince will be the surprise cherry on top of this year's festival.
