Keith's Song In New Eastwood Movie

Show Dog's Toby Keith accidentally wrote a song for Clint Eastwood's new movie The Mule (out Dec. 14). Keith shared a cart with Eastwood at the latter's golf tournament in May as the 88-year-old actor was preparing to depart for the three-month film shoot. Keith asked, "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 roll "Don't Let The Old Man In" over the movie's closing credits.
