Cover art for Roberta C. lyrics by Casiotone for the Painfully Alone

Not well read myself but the authors listed at the start:

Carson McCullers, "Her first novel The Heart Is a Lonely Hunter explores the spiritual isolation of misfits and outcasts of the South."

Flannery O'Connor, seems to deal a lot with religious ethics and morality

And maybe Jerome K. Jerome (not sure) he doesn't seem to fit.

As for the Change and the note, being the pessimist I've always looked at it was suicide. Though it could be looked at in a more positive light as the title of her book she's going to write (Do good Scabble players also make good writers)

Someone who's read works by the above could probably draw more light on to their (certain) significance to the meaning of the song.
