Picture the situation I was in, with a religious fanatic family. As a young child I was dragged into church and forced to endure one repetition after another of songs literally drenched in blood and self abuse. Is it any wonder that in self defense I began to recite limericks, ditties and anything else I could think of to block out the torrent ? Within a few years I became adept at multitrack tune recall. All these years the psychologists have been asking "do you hear voices ?" Absolutely not idiots, I hear music....
As an exercise in multitrack thinking, see if you can listen to the nutcracker

I had it reduced to a simply melody in about 15 minutes.
All these years people have complained that I whistle off key. Wrong, I am on key but off your track.....
