In Ronald Neame's Tunes of Glory, the incomparable Alec Guinness inhabits the role of Jock Sinclair--a whiskey-drinking, up-by-the-bootstraps commanding officer of a peacetime Scottish battalion. Sinclair is a lifetime military man, who expects respect and loyalty from his men. But when Basil Barrow--an educated, by-the-book scion of a traditionally military family--enters the scene as Sinclair's replacement, the two men become locked in a fierce battle for control of the battalion and the hearts and minds of its men.
