Country music star and proud American Toby Keith showed his support for the U.S. military in a special moment at his Atlanta concert Thursday.

Keith brought members of the military on stage at Aaron's Amphitheatre to sing "Courtesy of the Red, White, and Blue" in honor of those killed in the Chattanooga shooting July 16.

Most heartwarming of all: Keith welcomed the mother of Lance Cpl. Skip Wells, a Marine from Cobb County who died in the shooting.

The song starts with these words:

American Girls and American Guys
We'll always stand up and salute
We'll always recognize
When we see Old Glory Flying
There's a lot of men dead
So we can sleep in peace at night
When we lay down our head

Keith strummed an American flag guitar throughout the song, and fans took to social media to show their appreciation for the special moment.

Channel 2 viewer Amy Cromer said, "It was so beautiful to see and be a part of! Thankful for all our service men and their sacrifices. Proud to be an American. I hope things like this can be used to remind everyone how thankful we should be to be 'Made in America.'"
