"Words" is a song sung by the Bee Gees, released in 1968. They wrote this after getting in a few arguments and realizing the power of words - how they can make you happy or sad. Barry Gibb sang lead vocals.
The Words refer to Sarah's line that she could never remember until the end: "You have no power over me." The Words can also refer to the line that would summon the goblins: "I wish the goblins would come and take you away, right now."
