The one time I saw Bob Zentz, he added another verse to this song:
This is a verse for all the other people
All the other people who fucked up my life
Some by invention, and some by intention
And some I won't mention, because of my wife
He had made a reference earlier to Gordon Bok having made up a "truly awful" verse to the song. I suspect that this was the verse he was referring to.His wife was sitting next to him on the stage when he sang the song. She grimaced at this verse. Come to think of it, she might have been the one who used the phrase "truly awful".
