My baby makes me proud   Lord don't she make me proud   She never makes a scene   By hangin' all over me in a crowd      'Cause people love to talk   Lord, don't they love to talk   But when they turn out the lights   I know she'll be leaving with me      When we get behind closed doors   Then she lets her hair hang down   And she makes me glad that I'm a man   Oh, no one knows what goes on behind closed doors      My baby makes me smile   Lord, don't she make me smile   She's never far away   Or too tired to say I want you      She's always a lady   Just like a lady should be   But when they turn out the lights   She's still a baby with me      When we get behind closed doors   Then she lets her hair hang down   And she makes me glad that I'm a man   Oh, no one knows what goes on behind closed doors      Oh, no one knows   What goes on behind closed doors   Behind closed doors, behind closed doors   Behind closed doors
