How Great

Undoubtedly the highlight of the Academy of Country Music "Girls' Night Out" concert: Vince Gill and Carrie Underwood. Matching what may be the purest voice in country music with a guitar virtuoso and singer like Vince Gill is quite a combination.

(My old computer wouldn't have been able to keep up, but if you have one that can . . . choose 1080p in the resolution selector in the lower right, and full screen for a knock-out version of this song.)

And purely in the interest of passionate performing, I'm adding this duet by Ronnie Dunn and Jennifer Nettles—I don't think there are two singers anywhere that make you believe they are singing something that's painfully true more than these two. Until I checked, I didn't realize this song was written by the amazing Patty Griffin -- on her A Kiss in Time album.
