During last night’s Grammy’s Beyoncé sang “Take My Hand, Precious Lord” to lead into John Legend and Common’s performance of “Glory” from the film Selma. Now, in a behind-the-scenes video, the singer and those who accompanied her discuss the song and its relevance.

“I felt like this is an opportunity to show the strength and vulnerability in black men,” Beyonce explains in the video.

The song has been cited as a favorite of Martin Luther King, Jr., and in the film Selma, Mahalia Jackson, played by Ledisi, sings it to him. (The fact that Beyoncé sang the song at the Grammys instead of Ledisi was a point of contention for some.)

“My grandparents marched with Dr. King and my father was part of the first generation of black men that attended an all-white school,” Beyoncé explains in the video. “My father has grown up with a lot of trauma from those experiences. I feel like now I can sing for his pain. I can sing for my grandparents’ pain. I can sing for some of the families that have lost their sons.”
