With deep Southern soul in his voice and pride in his heart, American Idol finalist John Foster delivered one of the most moving performances of Season 23 — a heartfelt tribute to his two military veteran grandfathers.
Taking the stage during the live finale, the 18-year-old Louisiana native performed Toby Keith’s “Courtesy of the Red, White and Blue (The Angry American),” and it was clear from the first note that this wasn’t just a performance — it was personal. With his grandfathers watching from the audience, Foster sang with conviction, honoring both his family and the countless veterans across the country.
The crowd was on their feet before the song was even over. Judge Carrie Underwood looked like a proud mom, glowing with admiration. All three judges gave Foster a standing ovation and praised his emotional delivery and confident stage presence.
Foster, who beat out more than 120,000 hopefuls to make it to the top three, stood beside fellow finalists Breanna Nix and Jamal Roberts during the May 18 finale. With just minutes to impress the nation one last time, he chose a song that reflected both his patriotic spirit and personal story.
Mentored by Jelly Roll, Foster shared in rehearsals how overwhelmed he’s been by the support from fans across the country. But it was that finale moment — guitar in hand, grandfathers proudly watching — that truly showed the heart behind the artist.
Lionel Richie praised Foster for picking the “perfect song,” even joking that he could have a future in politics. Luke Bryan commended his growth, saying he’s watched him become a fully formed artist right before their eyes. And Carrie Underwood told him, “You gave us everything tonight — your voice, your pride, your story. I’m so proud of you.”
What made Foster’s performance shine wasn’t just his strong vocals, but the emotion behind every lyric. His tribute turned a country anthem into something deeply personal — a thank-you to his family, his roots, and to everyone who’s served.
As he wrapped up the performance, Foster looked into the crowd and said with sincerity, “If America thinks this little ol’ boy from Louisiana has what it takes, it would be the honor of a lifetime to be your next American Idol.”
Win or lose, Foster’s performance struck a chord — and proved that sometimes the most powerful moments come from singing straight from the heart.
