That's It For The Other One I: Cryptical Envelopment lyrics

The other day they waited, the sky was dark and faded,
Solemnly they stated, "He has to die, you know he has to die."
All the children learnin', from books that they were burnin',
Every leaf was turnin', to watch him die, you know he had to die.

The summer sun looked down on him,
His mother could but frown on him,
And all the other sound on him,
He had to die, you know he had to die
