Ah, the Supreme Warbler!  She is to popular music what Florence Foster Jenkins was to classical.  Were they parody?  Or unfortunate victims of a cruel and greedy commercial machine that used them up like oil and spat them out when they were spent?

But they knew exactly what they were doing.  What about Mrs. Miller?
