Don't Let The Old Man In Song by Toby Keith

Toby Keith wrote "Don't Let the Old Man In" in 2018 after a conversation with Clint Eastwood about living life to the fullest, regardless of age. The song was inspired by a conversation Keith had with Eastwood in May 2017 at Eastwood's golf tournament in California. During the conversation, the two shared a golf cart and Eastwood said, "I just don't let the old man in". Keith then wrote the song and sent it to Eastwood, who later included it in his 2018 thriller The Mule.
