Rough Idea of Love (1930)

Marjorie Beebe is a saloon singer, and Frank Eastman is the piano player and her boyfriend. He's got a roving eye, and she's making a play for the boss, who is crazy about her. So they slang each other, and beat on each other, and are very happy in their abusive relationship, which saloon owner Frank Sabini tries to break up, with machine-gun fire if necessary.
