IF they were to release TSWR to Country, then if anyone were to record Kara's part, Carrie would be the best option. Anyone who doesn't see that is delusional.

BUT, I would be okay with Miranda being on it, if not.
It's never going to happen either way so it's not even worth discussing further
...and I am STILL dying to hear those Kelly/Chris tracks

I think we may get it for Kelly's 6th album, depending on if it fits with the theme. I think KC once said we would probably hear it some day.
