Little Big Town took part in an all-star tribute to the Bee Gees during Sunday's (Feb. 12) 59th Annual Grammy Awards. In the last hour of the show, the country quartet shared the stage with Tori Kelly, Andra Day and Demi Lovato for a mash-up of some of the band's biggest hits.

Lovato took the stage first, dressed in a silver one piece while she belted the band's iconic "Stayin' Alive" as dancers performed behind her. Kelly followed Lovato and walked out with her electric guitar as she sang "Tragedy."

All the while, Bee Gees singer-songwriter Barry Gibb looked on from the audience with a big smile. Soon after, Little Big Town joined the tribute for a rousing performance of the band's 1977 hit "How Deep Is Your Love." Phillip Sweet started off the song with his mesmerizing deep vocals while donned in a black sequinned dress jacket. Kimberly Schlapman and Karen Fairchild stunned in a purple jumpsuit and red dress, respectively, while they joined in on impeccable harmonies with Jimi Westbrook.

A camera panned through the audience to find Gibb singing along to the tribute as well as Carrie Underwood, who was seated in the front row beside Rihanna.

A horn section added soul to the performance before all the acts united to close the tribute by joining in on "Stayin' Alive." The audience was receptive to the Kelly, Day, Lovato and Little Big Town mashup as they received a standing ovation.
