I have to do two songs today because I have to dedicate this one to my younger sister.  Not because she was a bad girl, at least not around me, but because she wore the vinyl off this album (that’s right vinyl).  So here is Donna Summer with Bad Girl which was a chart topper on this day September 4, 1979.  Gioveolympus has put together a really good video with a demo version of Bad Girls from 1979 that I haven’t heard before.
