See Rascal Flatts Crash a Karaoke Party — and Hear Their New Song 'I Know You Won't'

Rascal Flatts' tenth album, Back to Us, is out on May 19

Surprise! Rascal Flatts does karaoke night.

In a video shared exclusively with PEOPLE, the band is seen giving two unsuspecting ladies the ultimate fan experience when they crash a Rascal Flatts karaoke party, and hop on stage to sing along “Bless the Broken Road” with them. (The guys even performed their cover of “Life Is a Highway,” for the crowd at Wanna B’s in Nashville, before they headed out.)

“If they’re better than us then they can go out on the road instead of us, and we’ll collect the money,” teased Jay DeMarcus.

“I think it works out,” added Gary LeVox. “Even deal.”

“Business 101,” echoed Joe Don Rooney.

But Rascal Flatts fans may have a new karaoke go-to, as the band also just shared a new song, “I Know You Won’t,” off of their upcoming album, Back to Us.

“It’s an amazing project,” LeVox told PEOPLE of their tenth record while at the iHeartCountry Festival in Austin, Texas on Saturday.

“It’s some of the best stuff we put out in a long time,” continued LeVox. “We had all of the time in the world to do it, which was nice.”

Back to Us is out on May 19.
