Not being a professional folksinger myself, I have no idea why anyone should quit so a little background research is needed. Understanding why anyone chooses to be a professional folksinger in the first place is useful background information.

Captain Birdseye's original posting contained a non-sequitur. Just because someone ceases to be a professional folksinger does not mean that they cease to be a folksinger, leave the scene and leave it creatively poorer.
