Grammys: John Legend, Demi Lovato, Meghan Trainor Pay Tribute to Lionel Richie

Luke Bryan and Tyrese Gibson also took part in the medley featuring some of Richie's biggest hits.

The Grammys took a step back into the 1970s and '80s on Monday night with a star-studded tribute to Lionel Richie.

Demi Lovato, John Legend, Luke Bryan, Meghan Trainor and Tyrese Gibson paid tribute to the legendary singer with a medley of his hits.

Legend kicked off the tribute with 1977's "Easy," a hit by the Richie-fronted Commodores, followed by Lovato with 1983's "Hello," Bryan with 1984's "Penny Lover," Trainor with 1983's "You Are" and Gibson with 1977's "Brick House," another Commodores hit.

At the end of the tribute, all of the singers joined Richie back onstage for a performance of 1983's "All Night Long."

The tribute came two days after Richie was honored as the 2016 MusiCares Person of the Year at a benefit gala dinner and concert. The 26th annual event supported MusiCares, which ensures that music people have a place to turn in times of financial, medical and personal need.

Performers at Saturday's concert included Yolanda Adams, Dave Grohl, Lenny Kravitz, John Legend, Rihanna, The Roots, Usher, Pharrell Williams, Stevie Wonder, Leon Bridges, Luke Bryan, Ellie Goulding, Demi Lovato, Chris Stapleton and Florence Welch. Rickey Minor served as musical director for the Jimmy Kimmel-hosted event.

Richie was honored for his creative accomplishments as well as his charitable work, which has included support for causes from AIDS and human rights to famine, poverty, human trafficking and women's issues. He also is a longtime contributor to the United Negro College Fund.
