The Song Choice and Fan Reaction

While the exact song they performed together on the Opry stage is often the subject of fan discussion, the moment itself centered on their shared connection and mutual respect.

During his time on the show, Underwood openly expressed how much Foster reminded her of her own children and her younger self. She had a "soft spot" for him and was deeply moved by his original song, "Tell That Angel I Love Her."

This mentorship is vital for up-and-coming artists. An endorsement from a star of Underwood’s caliber—an 8-time Grammy winner and platinum-selling artist—provides an unparalleled boost to an emerging career. The exposure from the duet video alone has introduced Foster’s music to millions of new listeners.

Future Potential: Will We Get a Studio Duet?

The live Opry performance has naturally led to fervent speculation about whether Carrie Underwood and John Foster will record a studio duet. While no official announcement has been made as of late 2025, the possibility is very real, given Underwood’s recent history of diverse and high-profile collaborations.

Underwood has shown a clear willingness to work with artists across the music spectrum in 2024 and 2025. Her recent collaborations include:

• Cody Johnson: They released the long-anticipated song "I'm Gonna Love You" and performed it together, earning multiple CMA Awards nominations.
• Papa Roach: She surprised fans by collaborating with the rock band on the track "Leave a Light on (Talk Away the Dark)," even performing it live in Las Vegas.

These recent projects demonstrate that Underwood is actively seeking out unique and meaningful collaborations. A studio duet with John Foster would be a natural extension of her commitment to country music’s future and a powerful way to formally introduce his "old soul" sound to a wider audience. If they were to collaborate, a song that explores themes of faith, loss, or small-town life, perhaps an official recording of "Tell That Angel I Love Her" with Underwood’s harmonies, would be a massive success.

The live Opry duet was a moment of pure musical magic, blending the legacy of a superstar with the promise of a new voice. Whether or not a studio track materializes, the viral performance has already cemented John Foster’s place in the country music conversation, thanks to the generous spirit and enduring mentorship of Carrie Underwood.
