This tour seemed too big for the type of vocalist she is and the fact that she sings 100% live from the beginning. I was shocked when the tour dates were announced a year or two ago. Too much for her. She pretty much made it to the end. So no jokes needed. That said it is true that her voice is extremely beautiful but doesn´t seem to be that strong. And I´m not talking about power. Her voice seems to be fragile. Nothing wrong with it. I just think a tour like this one is too much. And yes it is a miracle that Whitney, Celine and Mariah´s voices lasted what they lasted based on the amount of work they did and the songs they constantly recorded. Crazy. They are the vocal trinity for a reason. Don´t care who gets hurt by it and the fact their fave is not on that level :)
