If you've ever wondered what hanging with The Rolling Stones would be like, you can get an idea by stopping by a cannabis dispensary. That's because the iconic rock band keeps about as much weed on hand as a local pot shop, according to Mark Mothersbaugh of Devo, who got to jam with the Stones in the studio in the 70s after a chance encounter with drummer Charlie Watts.

"[W]e were recording at the Power Station and they were remixing old songs downstairs," Mothersbaugh told Rolling Stone recently. "And this old guy with a big, fat sweater and gray hair came upstairs and said, 'Would someone here play synthesizer on a song for my band?' And I look at him and it was Charlie Watts. So I went downstairs and there was more marijuana than I’d ever seen in my life. Everybody got super stoned. And there was a vocoder that we’d borrowed from Bob Moog to use on the album. I didn’t have a microphone with a quarter-inch jack for it, so I got Mick to put a set of headphones on sideway so one of the earpieces was over his mouth. He sang into it while I played notes on a keyboard into the vocoder."

The gig involved recording a synth track on the song 'Worried About You.' But you haven't heard their version of it because Keith Richards hated it so much, he nearly went into a homicidal rage.

"The next day, they played it for Keith Richards and he later told my brother, 'Who played that synthesizer part? I’m gonna stab him!' [Laughs] So Keith hated it, but there’s a little of it still in the fadeout and that’s about it."
