It was an all star lineup on last weeks TV special "Girls Night Out: Superstar Women of Country". However, the breakout performance was a gospel duet with legendary country crooner Vince Gill and country ingenue Carrie Underwood. The two performers sang "How Great Thou Art" that amazed the audience and a video of the performance quickly went viral over the weekend.

Searches for the Underwood/Gill rendition of the song spiked a whopping 362% on Saturday, according to Yahoo! data.

Even the stars in the audience seemed to be amazed and transfixed on the two as they moved the audience.

Needles to say that even before the end of the song, the two were receiving a standing ovation. Carrie Underwood  gave Vince Gill a big hug and wiped a tear or two from her eye. Yes indeed, they "had church" that night.
