Contrary to widespread belief, "N.I.B." doesn't stand for "Nativity in Black." It simply refers to Bill Ward's goatee in 1969; the band joked it was shaped like a pen nib. The song is about the devil, but in a nice twist, it's about Satan changing his ways and falling in love. They never reveal the name of the lucky lady who gets to take Lucifer's hand, though. "Follow me now and you will not regret," Satan says to his love. "Leaving the life you led before we met/ You are the first to have this love of mine/ Forever with me 'til the end of time." An eternity with Satan in hell doesn't seem like a great deal for this woman. He needs to think of some better pick-up lines.
