What is this that stands before me?
Figure in black that points at me.
Turn around quick and start to run.
Find out I'm the chosen one.

Verse 2 (w Riff B):

Big black shape with eyes of fire,
Telling people their desire,
Satan's sitting there, he's smiling,
Watches those flames get higher and higer.
