Lady Gaga touched scores of hearts with a beautiful and somber moment during her headlining set at the 2017 Coachella Valley Music And Arts Festival on Saturday. Her 2016 album Joanne features a bonus track, "Grigio Girls," which is about her longtime friend Sonja Durham, who is battling stage IV cancer. During her headlining set on weekend two of Coachella 2017, Gaga dedicated an acoustic version of her song "Edge of Glory" to her.
