John Mayer headlined a gig at Nashville’s Bridgestone Arena last night (Aug. 8) as news broke that Glen Campbell had passed way after a lengthy battle against Alzheimer’s.

Not surprisingly, the country legend, who also had a profound impact on the pop charts, influenced John’s career.

“I’m going to play this song with more love than precision,” said John. “I’m going to play it because it’s my favorite song in the world, and it was performed by Glen Campbell, who sadly passed away today. I’m going to play this for him. Whether I play it right or wrong, I’d rather have played it.”

The song John was referring to was Glen’s Grammy-winning single, “Gentle On My Mind.”
