Country band King Calaway stopped by The Ty Bentli Show to spread some holiday cheer this week.

The six-piece group—comprised of Chris Deaton, Simon Dumas, Chad Michael Jervis, Jordan Harvey, Austin Luther and Caleb Miller—crammed onto the set with their instruments and stirring vocals to perform “Happy Xmas (War Is Over),” which John Lennon and Yoko Ono wrote and recorded in 1971. The Vietnam War protest song has since become a holiday standard, with recordings by Neil Diamond, Jimmy Buffett, Carly Simon, Miley Cyrus and more.

King Calaway’s full interview and performance will air on The Ty Bentli Show on Dec. 23, but you can get a sneak preview of their rendition of “Happy Xmas (War is Over)” below.
