Demi Lovato, Tori Kelly, Andra Day & Little Big Town Pay Tribute To Bee Gees During Grammys

This year marks the 40th anniversary of Bee Gees' 1977 soundtrack album Saturday Night Fever, and to celebrate, several very talented artists came together on stage to honor the band with an amazing tribute performance. Demi Lovato, Tori Kelly, Andra Day, and Little Big Town all got in touch with their inner disco selves to recognize the blockbuster's 40th birthday.

Talk about disco diva, kicking off the tribute was Demi Lovato, rocking a low-cut, sequined jumpsuit as she took the stage to sing Bee Gees' iconic hit "Stayin' Alive." Demi was followed by Tori Kelly, who took front and center with her guitar as she performed the band's 1979 song "Tragedy."

Country band Little Big Town appeared next, nailing their gorgeous cover of "How Deep Is Your Love," before Andra Day followed the group with a performance of "Night Fever." Demi, Tori, and Little Big Town returned to join Andra to close out the tribute with "Stayin' Alive."

Bee Gees' Barry Gibb was in the crowd singing along throughout the performance.

Earlier in the night, Saturday Night Fever star John Travolta had introduced Keith Urban and Carrie Underwood, but was not around during the Bee Gees tribute performance. 

At some point during the Grammys, Gibb got to meet one of his tribute performers: Demi Lovato:

This was a preview of what's to come during CBS' upcoming concert special Stayin' Alive: A Grammy Salute to the Music of the Gee Gees (which airs on February 14th). The concert special will feature Demi, Kelly, Andra, and Little Big Town, in addition to Celine Dion, John Legend, Nick Jonas, Pentatonix, and Barry Gibb himself.
