Matthew McConaughey & Snoop Dogg Cover Willie Nelson

Where there is smoke there is fire, and usually Willie Nelson.

Recently Snoop Dogg and Matthew McConaughey joined forces like a band of Gypsies on the highway as they covered the Willie Nelson classic “On The Road Again” for a clip promoting their Apple TV 'Carpool Karaoke' episode.

The smoke was a clear indicator that this duo is FIRE. If Matthew’s flip-up shades aren’t cool enough to catch your attention, Snoop’s laid-back style featuring a leather stars embezzled jacket will do the trick.

Apple TV’s full episode is streaming now. See for yourself as this duo hits the streets covering smash hits like, “I Wanna Rock N Roll All Night,” Snoop jams like “Drop It Like Its Hot,” “Gin & Juice” and, of course, Willie’s classic “On the Road Again.”

Catch Snoop join his buddy Matthew again in the feature film, 'The Beach Bum' which is set to debut on the silver screen on March 29.
