Celine Dion. Went to see her show in Vegas and her voice is just effortless. A New Day at the Colosseum, think it was the end of 2005, her Dad had just died and it was one of the last shows before she went home to be with her family. I was never a fan before, neither was the missus, but we went because it was the top show in Vegas at the time, her voice is just incredible, and the emotion she puts in to it as well. Never forget that, no one else has even come close for me.
