I heard a song in a bar in London which I love, but I don't know the
artist or song title.  The majority of the song is an old woman with a
blues voice singing "all night long" over and over again with clapping
going on in the backgroun.  Then, every so often, a chorus of little
girls sings a verse or two in hand jive style (similar to what girls
sing when they're jumping rope), but I can't remember the lyrics. Does
anyone know the song (most importantly) and where I can purchase it?
