One of John Wayne's very few "singing cowboy" pictures. Seriously, out of nowhere, he just bursts into song! And the truly hilarious part is that it's not even Duke singing! It's some other guy singing while Duke moves his lips to the words and pretends to play the guitar! And you know what a distinctive, recognizable voice John Wayne has, right? Well, let's just say that the result is about as convincing as James Earl Jones lip syncing to Clay Aiken!
