Toby Keith says he is "deeply saddened" by the death of his bass player. Officials in Oklahoma say Carl "Chuck" Goff Junior died in a two-car crash in a rural area south of Oklahoma City.

The Associated Press reports that the wreck remains under investigation. The driver of the other vehicle wasn't seriously injured.

Toby Keith says in a statement that Goff has been a close friend for more than 25 years, serving as both band leader and bass player for the country music star.

Goff also had writing credits on two of Keith's songs: "Upstairs Downtown" and "You Ain't Much Fun," both of which appeared on Keith's 1994 album,
