Note from Jon Corelis: after writing this poem I decided to use it as lyrics for a song of my own composition. It hasn't gotten performed yet, but the software generated demo audio file (using "ah" sounds for the vocal, since I don't have a decent voice simulator,) on YouTube will give some idea of what a performance would sound like.
