One of tonight's biggest Grammy performances was 40 years in the making. In 2017, the Saturday Night Fever soundtrack turns 40, which called for a special tribute to the Bee Gees by the likes of Demi Lovato, Andra Day, Tori Kelly, and Little Big Town. Lovato happens to be celebrating a milestone of her own at this year's Grammys: She was nominated for her first Grammy award for Best Pop Vocal Album.

The performers threw it back to the '70s with a disco-i-fied medley of the golden oldie Saturday Night Fever hits. Demi Lovato kicked things off with super long Cher-worthy hair and a sparkly '70s-style beaded crystal Redemption look singing the classic "Stayin' Alive." Tori Kelly picked it up with an incredible version of "Tragedy," Little Big Town played a countrified version of their "How Deep is Your Love," and Andra Day joined in for an energetic version of "Night Fever."

To their credit, the Bee Gees' Barry Gibbs looked like he was on the verge of tears.
