Like "Do Ya," a section of "Boy Blue" exhibits anaphora:
I've seen bold knights, dropping down like flies.I've seen kings, rolling in the mire.I've seen God, point the finger of doom to our foes.I have fought in the holiest wars.I have smashed some of the holiest jaw.I've been jailed, been impaled, and been dragged through the world.
The repeated "I've (seen)" indicates the amount and variety of the narrator's experience.
