Glen also battled alcohol during a stage in his life and tells Nashville’s daily newspaper The Tennessean, “I think Keith is going to come out of it OK. I’ve got to call him and talk to him about it.” Glen adds that he went through rehab at the famed Betty Ford Clinic in California, and says, “If his is anything like Betty Ford, I think he will come out of it great because you see so much in there. You are shown why and how you get there.” Keith checked himself into the Cumberland Heights facility in Nashville on Oct. 20 for treatment of alcohol abuse.
