United Kingdom, June 17 -- Sir Rod Stewart "begged" for a longer set at Glastonbury.

The 80-year-old singer will play the coveted Legends slot at the festival in Worthy Farm, Somerset, South West England, later this month and he is finding it "difficult" to put his set list together because he won't be on stage for as long as he'd like to be, which he fears will mean fans are left disappointed.

He told the new issue of Radio Times magazine: "It's difficult because they only gave me an hour-and-a-quarter slot. So I begged them: can I do another 15 minutes? Because usually I play for two hours.

"It means that there's a lot of songs that people love that I won't be able to play - and I've got three guests coming on."
