Toby Keith just released a new single that will be featured in Clint Eastwood's new movie "The Mule". The single is titled "Don't Let The Old Man In". Toby got the idea for the song after a conversation he had with Eastwood at a charity golf tournament. While spending the day partnered with Eastwood on the links, Toby and Clint discussed Clint's upcoming 88th birthday. Toby asked, "What keep ya going?" and Eastwood replied, "I just don't let the old man in!" Toby said instantly he knew there was something to that line for a new song. Check out my interview below to hear how it came to be!
