Most songs have meager beginnings. You wake up in the morning you throw on your suspenders and you subvocalize and just think. They seem to form like calcium. I can't think of a story right off the bat that was that interesting. I write things on the back of my hand usually and sing into a tape recorder.
I taught in a small teacher's college for three or four years at which point all the administrators got a pay raise and the teaching faculty didn't.
