NIB

Nativity in Black, a song by Black Sabbath, original named because the drummers head looked like the nib of a pencil.

The chorus of NIB is:
Now I have you with me under my power
Our love grows stronger now with every hour
Look into my eyes you'll see who I am
My name is Lucifer please take my hand
