This film was the final pairing of John Wayne (Rocklin) and George 'Gabby' Hayes (Dave) on screen. The two long time on and off screen friends had first worked together on "Riders of Destiny" (1933). Hayes was billed as just George Hayes, played Charlie Denton and Wayne played the role of singing cowboy and gunslinger Singin' Sandy Saunders. The two actors were very close in real life. Wayne's children thought of Hayes as an uncle and Hayes often described Wayne as the son he always wanted.
