After Kris Kristofferson‘s death on Saturday (Sept. 28), George Strait is remembering the late legend for his world-classic songwriting talents and his kind spirit.

Strait and Kristofferson weren’t personal friends, but in his tribute, the King of Country says that Kristofferson’s graciousness still shined through in every encounter they had.

“I knew him on a professional level only, but I always felt like it was more, because of the kindness and respect he showed me on the times we met,” Strait recalls. “I’ll treasure those times forever.”

He also says that, just like Kristofferson’s many fans, he’s grieving the loss of a one-of-a-kind musical talent.

“Artists and songwriters of this caliber come along very rarely and he certainly made his mark on the world,” Strait writes. “My family, like most people, were huge fans and we will all miss him.”
