Sir Mick Jagger - Mick Jagger Fuels Rolling Stones Glastonbury Rumour

The Brown Sugar hitmakers have never performed at the three-day rock event, which was launched in 1970 and is widely regarded as the U.K.'s leading summer festival.

Fans have speculated Jagger and his bandmates could be lining up to fill this year's 'legends' slot - the Sunday night headline set on the main stage - since they reunited for a series of 50th anniversary gigs last year (12), and the singer has now implied the speculation is correct.

He tells Britain's NME magazine, "Well, I'm just looking at what offers are coming in for this year and sorting them out. I hate announcing things when they're not booked. People are always like. 'Yakety yak, you didn't do that in the end', and I say, 'Well, yeah - we never really announced it!'

"All I'm doing at the moment is sifting through the possibilities, looking at the dates and how each one can fit in and so on. And then we'll see what we come out with... There are other things in the world, you know, apart from Glastonbury! But then again, Glastonbury is very important. It seems to be very important to my children - highlight of their year!"

Pressed on the issue, Jagger hinted an offer for the Sunday night has already been made by festival organisers, saying, "But is it going to be rainy on the Sunday?... Isn't it nearly always rainy on the Sunday?"
