Watch: The Lumineers join Noah Kahan for 'If We Were Vampires ...

The performance took place just two hours before the release of "Up All Night," a new collaboration between James Bay, The Lumineers, and Noah Kahan.

Noah Kahan and The Lumineers just love to perform together.

The band’s founding members, Wesley Schultz and Jeremiah Fraites, joined Kahan atop the Green Monster at Fenway Park in Boston on Thursday for the Jason Isbell song “If We Were Vampires.”

“I’d like to bring out some of my earliest and biggest influences, the incredible Lumineers,” Kahan told the crowd.

The performance took place just two hours before the release of “Up All Night,” a new collaboration between James Bay, The Lumineers, and Noah Kahan. Kahan and The Lumineers’ Wesley Schultz had previously released a version of “Vampires” in 2023 for the Spotify Singles series.

In 2023, The Lumineers invited Kahan on stage at Boston Calling. Kahan had been an earlier performer at the festival and a crowd favorite.

The Lumineers also returned to the stage alongside other guests, including Gracie Abrams, Bay, and Mt. Joy, later in the night for Kahan’s “Stick Season” finale.
