The rocker says he loved hanging out by the bookshelves in his local library in Kent

The Rolling Stones‘ Keith Richards has admitted he owes library fines going back 50 years.

Although he’s better known for his hard-partying ways, he told The Sun that hanging out by the bookshelves was one of his favourite pastimes as a teenager. “It was a place where you get a hint there was a place called civilisation,” he said of the library in Dartford, Kent. “I still owe fines from about 50 years ago.” According to the newspaper, the cost could be as much as £20,000.

Earlier this week (May 19), The Rolling Stones were joined onstage by Dave Grohl at their gig in Anaheim, California – watch footage of it below. The Foo Fighters frontman, who duetted with Jagger on the ‘Sticky Fingers’ track ‘Bitch’, is the latest guest to crop up at the Stones’ ’50 And Counting’ gigs. Tom Waits and John Meyer have also appeared, as has Katy Perry, who got onstage with the band in Las Vegas to duet on ‘Beast Of Burden’.

The Rolling Stones return to the UK for their Glastonbury headline set on June 29 and a pair of massive gigs in London’s Hyde Park on July 6 and 13.
