Standin' on my front porch   Grabbed her and I kissed her   Boy   (I)   Was surprised when I saw her little sister      Lights out, lights out   I'm glad the lights was out   Sister knows   (What)   It's all about   What to do when the lights go out      Mother looked at me   She was peepin' through the window   Way she looked at me   You'd have thought I was her sister      Lights out, lights out   I'm glad the lights was out   Sister knows   (What)   It's all about   What to do when the lights go out      Lovin' on the front porch   Took mama's swing   I can almost hear   Those weddin' bells ring      Lights out, lights out   I'm glad the lights was out   Sister knows   (What)   It's all about   What to do when the lights go out      Now we're married   And we got a little house   Had to marry little sister   'Cause the lights went out      Lights out, lights out   I'm glad the lights was out   Sister knows   (What)   It's all about   What to do when the lights go out      Now we're married   And we got a little house   Had to marry little sister   'Cause the lights went out      Lights out, lights out   I'm glad the lights was out   Sister knows   (What)   It's all about   What to do when the lights go out
