I just finished reading the book, and after listening to this song, I was blown away by all of the connections, for example:
the first stanza is about Jack turning everybody againt Ralph, because you could refer to the tribe as a herd or a mob, and after awhile they were all against Ralph and the littluns.
"Now you lead the way,
show the light of day. "
This refers to Ralph waiting for the night to end, because he thinks Samneric wouldn't say these things in the daytime.
The connections are almost haunting!
