Mick Jagger says that he asked Bono for advice ahead of The Rolling Stones' debut appearance at Glastonbury this year. He also received a letter from Coldplay's Chris Martin encouraging him to play the headline slot.
Speaking to today's Observer newspaper, 70-year-old Jagger said: "It's not your stage and it's not your crowd per se – people have bought their tickets before any acts have been announced. I know U2 didn't have the best of nights [in 2011], although the weather didn't help."
Jagger asked for Bono's advice on whether the Stones should appear, while Chris Martin wrote him a letter listing the reasons why the group should. "Chris was very sweet. The truth is, though, that they'd never actually asked us – and the first time they did, we said yes."
The Stones man and festival veteran who will become a great grandfather next year is currently working on a film about Elvis Presley, based on the Peter Guralnick book Last Train to Memphis.
"There's a Taschen book of the journey that Elvis took from Memphis to New York to sing Hound Dog on TV in 1956, and in every picture he just looks so super glamorous."
Jagger added that he never met Presley: "No. John Lennon told me not to."
