Carrie Underwood's high-pressure moment of having to sing at the Presidential Inauguration when the tech goes haywire has gone viral, as the singer shrugged it off and sang "America, The Beautiful" a cappella, getting rave reviews for her "cool under fire" response. Jason Aldean was on "Fox & Friends" yesterday morning and praised Underwood for her professionalism. "First of all, it’s a hard song to do anyway, and when you’re supposed to be singing to a track and that’s what gives you pitch reference for the song. To not have that, for her to just kinda say, ‘All right, listen, we’ll go.’ That’s a big move and that’s a pro move on her part, so I thought it was great.” See Jason's interview with "Fox & Friends" below
