The Rolling Stones frontman, who has resumed the band's '14 On Fire Tour' after the death of his girlfriend, fashion designer L'Wren Scott, thinks the controversial decision to book Metallica as the first heavy metal band to play Glastonbury will pay off.
Sir Mick told The Sun newspaper: ''I've seen them live and they're going to be great.''
The singer, who headlined the festival at Worthy Farm in 2013 with band mates Keith Richards, Ronnie Wood and Charlie Watts, also claimed he had a ''great time'' at the event and their success has seen the group sign up for more festivals this summer.
Metallica will close the line-up on Saturday, June 28, with headline acts Kasabian and Arcade Fire also on the bill.
Drummer Lars Ulrich said: ''To be honest with you, we didn't sit around and have a big conversation when the call came.
''In Metallica we have a saying called a 'no-brainer'. Headlining Glastonbury is a no-brainer. We didn't need to sit around thinking about the pros and cons.''
The group are the first metal band to ever headline the festival in its 44-year history and admit fans have had mixed reactions to the announcement.
Meanwhile, Sir Mick and his band mates performed their first gig on Monday night (26.05.14) since L'Wren's suicide two months ago.
They took to the stage at Oslo's Telenor Arena in Norway and played to a sold-out crowd of more than 23,000 people.
