I hope Shania's voice can make it. But, if she has to, I'd rather she cancel some shows than for something to happen to vocal chords or something.

At least she has tomorrow (Thursday) off. Maybe her voice will be able to recover. Does she have any extended breaks (of at least a week) during this leg of the tour? If so, maybe her voice will be able to recover and she'll be able to make it.

As I said though, she needs to do what is best for her health; I have a feeling though that if she does need to cancel, Mutt or some of her people will have to convince her because I know she won't want to disappoint fans by cancelling/moving dates. But, we fans would understand.
