It was an evening when the worlds of film and rock 'n' roll collided.
The UK premiere of the Rolling Stones "rockumentary" Shine A Light has been held in London's Leicester Square, in front of hundreds of adoring fans.
The red carpet had never seen so many pairs of skinny jeans - or as many rock haircuts.
All four Rolling Stones - Mick Jagger, Keith Richards, Charlie Watts and Ronnie Wood - attended the screening.
"It is only a little taster, just scratching the surface of our career, but it was good fun," said guitarist Wood, 60.
Director Martin Scorsese mixed backstage antics, interviews and archive TV clips with live concert footage.
"It's fantastic," yelped an excitable Jagger, 64, looking debonair in a green-striped scarf and tight black jeans, before being led into the cinema to chants of "Mick, Mick, Mick".
Oscar-winner Scorsese has said he had "a compulsion" to capture the 2006 performances from the Stones at New York's Beacon Theatre.
The result is an energetic, intimate, and humorous profile of the veteran rock 'n' roll band.
Wood said working with Scorsese for a second time was the highlight of the process.
"I did The Last Waltz with Scorsese and 30 years later I end up doing this other picture. I said to him I look forward to doing the third, so perhaps I'll be in The Departed II, who knows?"
The old rockers mingled with the young guns, in the shape of bands like Oasis, but onlookers were hard-pressed to identify the 60-something stars from afar.
Normal film premiere protocol flew out of the window as the Stones weaved from press, to fans, to press, and back again - much to the delight of those who had queued for hours in the drizzle.
They signed autographs, danced, pouted and strutted to their music - Brown Sugar, Jumpin' Jack Flash - which blasted across the square.
Liam Gallagher and wife Nicole were among the celebrities
Oasis frontman Liam Gallagher, TV presenter Alexa Chung, DJ Alex Zane, Mighty Boosh star Noel Fielding and actor Sean Maguire were among the other stars on the red carpet.
Drummer Charlie Watts, dressed in a smart velvet suit and white cravat, admitted he hated seeing himself on screen and played down his part.
He said: "I didn't do anything, I just played the drums. There was nothing to do.
"It's very well filmed, beautifully filmed and it's a show that happened to be a good night!"
It was left to guitarist Keith Richards, dressed in pirate-chic with his hat at a jaunty angle, to strike a more poignant note.
"It's kinda weird because I'm just a guitar player," he said.
"My grandfather used to play violin for the crowds here, he was a busker, so in a way it's one for grandad."
But he couldn't resist a quip when asked if he'd ever go in front of the cameras again.
"I'd do Gone With The Wind," he said. "And my King Lear is fantastic."
