Authorities say the bassist for country music star Toby Keith has been killed in a two-car crash in Oklahoma.

The Cleveland County Sheriff’s Office says 54-year-old Carl “Chuck” Goff Jr. was killed in the crash Wednesday night in rural Cleveland County, about 35 miles south of Oklahoma City.

Keith said in a statement that he’s “deeply saddened” by Goff’s death. Keith says Goff was a close friend for more than 25 years, serving as band leader and bass player.

Goff shared writing credits on “Upstairs Downtown” and “You Ain’t Much Fun” on Keith’s 1994 album “Boomtown.”

The two-vehicle crash remains under investigation. Authorities say the driver of the second vehicle wasn’t seriously injured.
