Keith Richards gave away one of his favourite guitars during the filming of new Rolling Stones rockumentary SHINE A LIGHT - as a mark of respect to Buddy Guy.
The guitar great joined the Stones onstage at New York's Beacon Theatre to perform Muddy Waters' Champagne + Reefer for the Martin Scorsese-directed concert film.
And always cool Richards was so taken by the magical moment, he handed over his guitar.
He says, "It's one of my favourites, too.
"That was straight off the top of my head: 'It's yours, baby.'
"With everything going on that night, with this movie, I thought, 'This is my respect to Buddy and to Muddy and all the other guys who turned me on.'"
