Best: Reba McEntire, Miranda Lambert and Kelly Clarkson's Power Trio
It's been 15 years since Emmylou Harris, Linda Rondstadt and Dolly Parton released their final Trio album, and another group of all-star females should consider filling that vacancy. What began as a tribute to Reba McEntire, with legends-in-training Kelly Clarkson and Miranda Lambert trading harmonies on 1984's "How Blue," turned into an all-out class 'n' sass fest once McEntire grabbed a microphone and joined the others on "Fancy." The result? The first (and longest) standing ovation of the evening.
