Who Are Your Mt. Rushmore of Singers? Shari & Chris Take on the World

Who is the best of the best? We all have an opinion on this subject, there's even a Rock & Roll Hall of Fame dedicated to it. When I saw this subject come up on Facebook, I thought this would be a perfect topic to discuss with Chris in the next installment of Shari & Chris Take on the World. For my choices, I went with pure singing talent, not stage presence, looks or popularity. You can say what you will about shows like American Idol, X Factor and America's Got Talent, but I absolutely love to see someone get on stage who has raw talent, who can truly sing. Feel free to comment below with your choices for who would go on the Mount Rushmore of singers.
