Betsy Smittle, Garth Brooks' half-sister and a longtime member of his band, died Saturday (Nov. 2) in Oklahoma at age 60. A cause of death has not been announced, and funeral services are pending in Tulsa, Okla.

Smittle was a bass guitar player and vocalist who toured with Brooks' band, Stillwater, for several years.

In addition to her work with Brooks, Smittle released a solo album, Rough Around the Edges in 1994. She also toured with Oklahoma singer Gus Hardin and appeared on her 2001 album, I'm Dancing As Fast As I Can
