But Brad bonded with them over super normal things.
The singer-songwriter was recently on the Bobby Bones Show talking about his relationship with the famous band. The first question was, of course, how do you become friends with the Rolling Stones, to which Brad had the best quip, "There's a course you have to take online."
In reality, though, Brad was able to connect with the rockers about music.
"Somebody gave me a tip, 'Mention the Louvin Brothers to Keith Richards,' and that was all I had to do," Brad said. "He was ready to talk about 'Satan is Real,' he loves that album."
And when he went to ask Mick Jagger to appear on "Drive of Shame" for his new album, Love and War, it was like going to dinner with an old friend.
"He picked the restaurant and I thought for sure he's got people who do that," Brad said. "I've never been here before, how did you find this? And he said TripAdvisor or something. he looked it up, 'It said this was great, I thought we should try it.'"
