Not a song - a story about the traditional singer Aunt Molly Jackson - wonder if anyone can verify it?
Alan Lomax heard that she knew a number of bawdy/bordering on the obscene Jack Tales, which she would never tell in public, and refused to allow to be recorded. When she was visiting his home one summer he set up a recorder under a table with the microphone hidden behind an air-conditioning grille, switched on the recorder and left it running.
Worked fine for a few minutes until another guest switched the air-conditioning on.
