Little Big Town added their unique harmonies to the Stanley Cup playoffs on Sunday afternoon (April 30). The country quartet were on hand to sing the national anthem prior to the Nashville Predators taking the ice for the third game of Round 2 of the playoffs against the St. Louis Blues.

Like Carrie Underwood and Luke Bryan before them, Jimi Westbrook, Karen Fairchild, Kimberly Schlapman and Phillip Sweet were decked out in Predators jerseys when they hit the ice at Nashville's Bridgestone Arena to perform the anthem in the Predators' first home game of Round 2 of the Stanley Cup playoffs. Hear their signature harmonies in the video above.

Underwood and Bryan both performed the anthem at home games during Round 1. The Preds and the Blues will face off again on Tuesday night (May 2).

Pro Athletes Who Went Country

Little Big Town have been busy otherwise, promoting their new single, "Happy People," which is the second single from their current album The Breaker. The group sat down with Willie Geist for a deeply personal interview on Sunday Today earlier Sunday morning and opened up about how personal tragedies they have faced have brought the band members closer together as a family. Those tragedies include the death of Schlapman's first husband in 2005 and the 2015 death of Westbrook's sister after battling cancer.

“We do take care of each other,” Karen Fairchild says.

“It’s the things that you walk through usually only with close family, but I think that’s how we all became family and it makes us stronger,” Westbrook adds. “I wouldn’t want to walk through any of this without these people.”
