Woodstock

Lots of old blues were deliciously bawdy, lots of double entendres and the like. Not all heterosexual either. Ma Rainey 's "Prove It On Me Blues" ,lines like "went out last night with a crowd of my friends must have been women cause I don't like no men"" on the album AC/DC Blues, a collection of old blues songs about gay and lesbian relationships.
And of course all the blues tunes referring to "jellyroll" or "jelly".
John Jackson- "girl named Irene, got good jelly but she's stingy with me" and his song Diddy Wah Diddy" with the line " I got put right out of church because I diddy wah diddied too much."
And have heard that the word "jazz" itself (or "jass") was at one time slang in certain subcuktures for sexual inrercourse. May well be. Do know that jazz was denounced as immoral and decadent by the prudes and moralists when it first came on the scene. Of course that was in large part because it was seen as black music, the same as rock and roll was.
