Kesha may wash her teeth with Jack Daniels, but damn, that girl has a great voice. The songstress has been dealing with a legal battle [1] against her former producer Lukasz "Dr. Luke" Gottwald for several years now. Because of her contract with Gottwald, she hasn't been able to create new music with anyone else. She has a court hearing on Tuesday, and fans are organizing a protest in support. Ahead of the hearing, a fan account for Kesha posted this video of the singer taking on the legendary "Amazing Grace" and really nailing her stripped-down version. Take a look, especially if you're thinking about going to the #FreeKesha protest!
