The performance was met with a standing ovation and moved many in attendance to tears, including the film's actors David Oyelowo (who played Martin Luther King Jr.) and Oprah Winfrey (producer and who played Annie Lee Cooper).
"It's a symbol for change," Common said of the Edmund Pettus Bridge when accepting the award for Original Song for "Glory." He continued to say that it "transcends race, religion, sexual orientation and social status... this bridge was built on hope."
"Selma is now because the struggle for justice is right now," Legend added.
Before invited to perform "Glory" at the award show, Legend and Common told Billboard that if invited they "would want to deliver the best performance possible." And, that they did.
The Ava DuVernay directed film is nominated for Best Picture and Original Song, with "Glory." Common and Legend beat out a"Everything is Awesome" from The Lego Movie (performed by Tegan and Sara and The Lonely Island), "Lost Stars" from Begin Again (performed by Adam Levine and Keira Knightley), "I'm Not Gonna Miss You" from Glen Campbell… I'll Be Me (performed by Campbell) and "Grateful" from Beyond the Lights (performed by Rita Ora).
