There was a time, where I was raised, when a public place with a string of blue lights under the eves and around the building was called, "House of blue lights".
They indicated a combination, nip joint, honky-tonk dance hall, juke joint, and was a place where self-respecting ladies would turn up their nose and look the other way while passing by on the adjacent road.
It was where folks went to dance the "Boogie-Woogie", and all the attending girls wore saddle oxfords and a jaunty bow in their hair.
Sadly, the local, "hard-siders", and "holy-rollers", had gotten the local laws to shut em all down before I got old enough to attend, but I had two uncles that were regular attendees; much to the chagrin of my old Gran-Gran.
For all I know there were no others in the world but the local one I recall, but I keep half remembering a song refrain about "House of Blue Lights" ? But,..it could just as easily be the song by George Clooney's aunt, Rosemary,.."Come ona my house sa, my house sa come on".
