I am pretty sure you are correct
“Birmingham Sunday” discusses the deaths of all four girls, while “Ballad of Birmingham” focuses on the death of one girl.
In "Birmingham Sunday" Richard Farina uses verses 2-5 to identify the name of each of the four girls, giving them their own verse in the song. In "Ballad of Birmingham" the mother refuses to let her child go down to the protests happening in the streets for fear of the violence. She sends her child to church instead. The church, however, is bombed and the daughter dies.
What do you think of when you hear monster? A green being with yellow teeth? or a killer who was a heart of stone, and an unquenchable thirst for blood? What words will you use to describe them? Malice, murder,slaughter,shameless.
