John Foster’s Duet with Todd O’Neill Brings Down the House on American Idol—“It Was Like a Nashville Recording Session Live on TV”

American Idol Season 23 has had its share of standout moments, but few have hit home like John Foster’s recent duet with fellow country powerhouse Todd O’Neill. Singing Jamey Johnson’s emotional classic “In Color,” the performance didn’t feel like a competition—it felt like a Grammy-worthy studio recording straight from the heart of Nashville.

From the first note, you could tell this wasn’t just two singers sharing a mic. Foster’s deep, soulful drawl fused effortlessly with O’Neill’s gritty edge, creating harmonies that were pure magic. They didn’t just sing the song—they lived it. The emotion, the chemistry, the authenticity… unforgettable.

His duet with O’Neill sealed it—Foster’s not just a contestant; he’s the real deal. Fans and judges alike can’t get enough.

A Heartfelt Tribute to Carrie Underwood—and a Full-Circle Idol Moment

In a special episode honoring Iconic Idol Moments, Foster paid tribute to none other than Carrie Underwood, delivering a moving rendition of “I Told You So”—a Randy Travis song that Carrie once famously performed on Idol herself.

“Carrie’s kind of been my voice on the panel,” Foster said. “She asked me to sing a second song during my audition—if she hadn’t, Luke would’ve said no. This is my way of saying thank you.”

During the performance, Foster took off his signature cowboy hat and sang directly to Carrie. Her response? A big smile and a glowing compliment: “I’m blushing! I love watching you grow every time you take the stage.”

Of course, Luke Bryan couldn’t resist a joke: “You know Carrie’s husband is a hockey player, right?” Carrie chimed in with a laugh, “He’s a big man!” Foster grinned and said, “All respect, all respect.”
