That evening, the band arrived to spend time with Guy to reminisce - they first met in a Chicago studio in 1964 - and watch some authentic blues performed by 86-year-old guitarist Jimmy Johnson, who has played with both Freddy and Albert King.

"Buddy's like a stand-up comedian the way he tells stories, and they were practically on the floor laughing," says Guy's publicist Annie Lawlor. "They mostly listened to Buddy. It's tough to get a word in edgewise when he's on a roll.

"They of course remembered B.B. [King]," adds Lawler. "They wanted to hear Jimmy Reed stories - Ronnie specifically wanted to hear about Jimmy Reed. These are stories only Buddy has and only he can give them. It was pretty incredible."

The Stones then sat at a table in the back of the club to watch Johnson's first set before making a point to shake his and his bandmates hands before heading out into the night.

"I can't think of any other club in the world that that can happen, where the Stones would all be there in the same room at the same time," says Lawlor. "I'm sure they have a hard time going out in a group like that for obvious reasons. If anything is going to bring them all in the same room at the same time, it's Buddy Guy, and thats pretty cool."
