In the video, three men start to sing the "Star Spangled Banner" near the check-out line at the Walmart location in Spring Hill, Tenn. More people joined in on the singing, resulting in a rousing patriotic performance, according to WKRN.
The video, captured by WKRN viewer Holly Redfern, was shared to the station's Facebook page. Tammy Daugherty Ver Steeg said that the local choir group Spring Hill HarMonix was responsible for the performance.
"We just wanted to go around our sweet little town and bring a smile to people's faces," Ver Steeg wrote on Facebook. "We also wanted to honor those fallen soldiers in Chattanooga. They were gunned down in public, and we honored them in public. America is a great country and we're proud to live here!! Amy Hall is the director."
Spring Hill HarMonix describes themselves as "a diverse choir of all ages and various styles but [with] one goal; make good music and have fun doing it."
"They are amazing people It doesn't surprise me that they are trying to lift people up in wake of these tragedies," wrote one Facebook user.
