Little Big Town didn't choose the most well-known Christmas song to begin their two-song set during the 'CMA Country Christmas' special on ABC Thursday night (Dec. 20), but their original a capella version of 'Children Go Where I Send Thee' is sure to be amongst the more talked-about highlights on Friday morning.

Prior to being introduced by host Jennifer Nettles, the quartet talked about their holiday traditions -- or at least they tried to. Between the four of them, they have three small children, whose adorable antics stole the show. Two-and-a-half-year-old Elijah -- Jimi Westbrook and Karen Fairchild's kid -- attacked the coffee table centerpiece like it stole his stocking.

The soulful a capella version of their first song showcased their unique, choral harmonies. Phillip Sweet's ability to dig low surprised even Nettles. He's a modern day Richard Sterban. After finishing, they were called over by Nettles to chat about their kids. Westbrook shared how his and Fairchild's son makes the holidays so much more special.

"It's just fun for the injection of that magic again in your life," he said. Soon, the band was taking their place on stage again, this time to sing 'Tennessee Christmas.' Kimberly Schlapman was showcased as the lead singer during the more familiar Christmas classic. She and Fairchild shared lead vocals, with the men hanging back to help with harmonies.
