Toby Keith is inspired by Clint Eastwood

The Country star shared a cart with Eastwood at the Oscar-winner’s golf tournament in May.
The 88-year-old actor-director was about to depart for the three-month film shoot on his new film, “The Mule”. Keith asked him, “How do you do it?” to which Eastwood replied, “I just don’t let the old man in.”
Keith wrote the song and sent it to Eastwood, who decided to feature “Don’t Let The Old Man In” over the film’s closing credits.
