I agree, Azizi. It is a typical double meaning song. I don't like the word coded; words like 'jelly' are (or were) well known slang to anyone who listened to Black jazz before WW2. I don't like 'double entendre' for these songs either, although this is the term often seen in articles about them. Any suggestions, Azizi?

In the semi-rural areas of the deep South until about two-three generations ago, for white folks this often meant listening from their car parked outside the joint, but open windows and doors let the sound out. Sometimes well-known performers passing through would play. Often one of the cars would be manned by a couple of sheriff's deputies. The white joints had country music, sheriff's deputies were there too but they sat at the bar or a table towards the back. I only saw them have to get on their feet once and that was in a white joint in Georgia when two customers had a mild disagreement.

For a spell (in the 60's if I remember correctly) )Lightnin Hopkins played engagements in a private club (white) in Houston. I never did get to hear him live; just bought a couple of lps which I still have.
