In the course of promoting his newly released album recently, much-celebrated songwriter, Elvis Costello (do you think he ever gets referred to as the spouse of Diana Krall?) was speaking about how he approaches his craft. He said he’d once been inspired to write a song about an “old, now vaguely respectable fascist”, but confessed that in order to do so, he “made up a fantasy” about the guy because it would have been “too tedious and… disgusting” to do otherwise.
A lot of songs are like that. You make some sort of drama or narrative to walk you past the stuff that’s on your mind. Otherwise, you’d just be writing an op-ed.
