Popular country singers abruptly stop concert to honor 9/11 victims with national anthem

Country music group "Rascal Flatts" took the cake when it came to remembering 9/11 victims on Tuesday. They halted their entire show and sang a tributary national anthem.

It seemed that the group woke up with that day on their minds right away. One member, Jay DeMarcus, shared an Instagram post way ahead of their upcoming show.

He asked the question America will forever ask:

"Do you remember where you were, 17 years ago today? I certainly do- and I never want to forget."

DeMarcus will also never forget those who sacrificed their lives for his freedom and that of all of America.

"I never want to forget the heroes that gave their lives that day, split-second decisions, personal sacrifice, life in the balance. The sacrifice continues, the war against terrorism is very real and happening around the globe."

He also acknowledged those who are currently on the frontline.

"Our freedom comes with a price, and there are brave service men and women who stand on the frontlines every single day ready and willing to pay it. Thank God for them, one and all. I'm honoured, grateful, and humbled."

The Rascal Flatts then went ahead to the show at the Red Rocks Amphitheatre in Colorado. They were greeted on the road with a huge display of 9/11 tributes right in the street.

In the parking lot, two fire trucks were parked parallel to each other and their ladders were elevated to the fullest extent. In between, a huge American flag swung from above.

DeMarcus shared a picture of the display and called it a "Beautiful tribute."

The show finally started. Right in the middle of it, the group stopped suddenly for what appeared to be an impromptu performance of the national anthem according to Classic Country Music.

The crowd sang along with the heartfelt rendition. At a couple points, one member turns the mic over so that the voice of the audience would prevail in the hall.

The Rascal Flatts, who are experienced in singing the most well-known song in the country, also gave a beautiful performance of it back in April 2018.

They opened for the Stanley Cup Playoffs on Thursday night in Bridgestone Arena. The gold-clad crowd erupted when the group consisting of Gary LeVox, Jay DeMarcus, and Joe Don Rooney were announced.

The packed crowd held supporters of the Predators and the Colorado Avalanche. They had just watched an elaborate video and were well-prepped for more action.

They did not anticipate the popular group since officials do their utmost best to keep the identity of performers a secret right before they actually come onto the stage.

So when the group finally did, the crowd was pleasantly surprised and extremely satisfied with the performance.

And back in 2016, the group was also part of a special mashup prepared for the Country Music Awards' 50th instalment.

They were among 30 other artists that were featured in a video titled "Forever Country." The incredible cinematography included the likes of Carrie Underwood, Blake Shelton, Tim McGraw, and many others.

Other bands such as Alabama, Little Big Town, and Lady Antebellum also played a role in the mashup which was directed by Joseph Kahn, a Grammy Award winner.
