As you know, the world of music lost a legend late last week. Etta James passed away from leukemia complications at the age of 73. It didn't take long for the tributes to start pouring in and one of the best came from Radio City Music Hall Saturday night. Kelly Clarkson, who has proven she can sing rock, pop and country, laid into Etta's R&B classic "I'd Rather Go Blind." This is AMAZING!
