The Oak Ridge Boys have been going out on their annual Christmas Night Out Tour for 25 years, but they decided to make last year's trek extra special -- and that decision paid off.

As part of their 25th Christmas Night Out Tour, the Boys added a one-night TV special to their show lineup in order to pay tribute to the American Legion, specifically for their work helping veterans who suffer from post-traumatic stress disorder (PTSD). The one-hour show, called A Salute to Christmas, aired in markets across the U.S. and was produced by Tracy Trost -- and it was the winner of the 2015 Telly Award for Outstanding Television Program.

“This project is very special because the heart of it is to bring attention to the needs of our veterans. For me personally, being able to work so closely with the Oak Ridge Boys has been a highlight in my career,” Trost says in a press release. “Winning this award just shows how excellent they and the American Legion are. I am honored to be a part.”

In addition to the Oak Ridge Boys, A Salute to Christmas featured Larry Gatlin and the Gatlin Brothers, the Martin Family Circus and Mary Sarah.

The ORB's lead singer Duane Allen says that supporting veterans suffering from the effects of PTSD is a cause close to the band's heart.

"PTSD can be a debilitating disease for servicemembers returning home, but it can be treated,” he says. “The American Legion’s work with veterans facing PTSD is among some of the most important in the country, and we wanted to help them support that work with the kickoff of our Christmas Night Out Tour.

"If this award can help us tell the story of the men and women suffering with PTSD, and of the help that the American Legion is providing to them, that’s a great thing," Allen continues. "We’re honored to have received this award, but we’re more honored that we got to be a part of helping those who’ve given so much to our country already."

The quartet — made up of Allen, Joe Bonsall, William Lee Golden and Richard Sterban — released a new album, Rock of Ages: Hymns and Gospel Favorites, earlier this year. The project is available for download on Amazon.
