Carrie Underwood and Vince Gill sing, "How Great Thou Art"

If you had been at the 2011 Academy of Country Music Awards a few weeks ago, you would have been in the company of hundreds of the biggest country music stars. You would have heard and seen an incredible lineup of the superstar women of country music. The event was later aired on CBS. But the biggest event of the night turned out to be a rendition of "How Great Thou Art" by Carrie Underwood with Vance Gill. The song drew an unexpected response -- and standing ovation -- moving many of the audience of veteran country performers to tears, Christian and non-Christian alike.
