John Mayer paid tribute to the late Glen Campbell appropriately in Nashville following the news of the country legend’s death at the age of 81 after a battle with Alzheimer’s.

About midway through the show, Mayer honored Campbell at the Bridgestone Arena with a solo cover of “Gentle On My Mind.” The track (originally penned by John Hartford) served as the theme to Campbell’s variety show in the late 60s.
