LOS ANGELES — One of Oscar night's best-received musical performances was wholly unexpected.
Darlene Love belted out that "I sing because I'm happy" when appearing onstage with the winners of the best documentary feature, "20 Feet From Stardom."
Love, best known for her work with producer Phil Spector in the 1960s, was one of the featured artists in the film about some of the music industry's best backup singers.
From the audience, Pharrell Williams smiled as she finished her song. Bill Murray pumped his fist and rose, and other spectators joined him in a standing ovation.
When it was time for U2 to perform their Oscar-nominated song, "Ordinary Love" from "Mandela: Long Walk to Freedom," Bono ended it with a shoutout: "Darlene Love!"
