Darius Rucker teams up with John Mellencamp for CMT Crossroads on Friday (March 24th). Taped in front of a live audience at Nashville’s Bridgestone Arena on February 24th, the two trade vocals on several of their big hits, including “Wagon Wheel,” “Alright” and Darius’ latest single “If I Told You,” as well as Mellencamp’s “Pink Houses” and “Cherry Bomb.”

It was pretty difficult for Darius not to be just a fan when he was onstage with the legendary performer. “That’s the hard thing for me is to not be out there fanboying the whole time and freaking out that I’m actually on stage with someone like John,” he says. “We were in rehearsals and he’s singing those songs, and I mean, I keep forgetting that I was supposed to sing too, because I just wanted to sit back and listen.”

The new episode airs Friday at 10pm ET on CMT.
