Blake Shelton wrote a touching tribute to his friend Joe Bonsall after his death.

From 1973 to 2024, Joe played in the country and gospel band The Oak Ridge Boys.

The 48-year-old Blake shared a picture of himself singing on stage with The Oak Ridge Boys on Tuesday.

No one knows for sure when and where the picture was taken.

“I’m so sad to hear about the death of my friend Joe Bonsall,” he wrote on his Instagram Stories.

“I’ve NEVER seen Joe when he wasn’t smiling and completely full of life.”

Blake went on, “He loved singing more than anyone I’ve ever met.”

“His family and his @theoakridgeboys brothers are in my thoughts and prayers.” Today we lost a very important person.

Blake put out the song “Doing It to Country Songs” with The Oak Ridge Boys in 2016.

Amyotrophic lateral sclerosis, which is also known as Lou Gehrig’s disease, led to his death.

ALS is a neuromuscular disease that can’t be cured. It affects the body’s voluntary muscles.

Fans found out about the singer’s diagnosis in January 2024, four years after he had been sick.
