Bill, I'm convinced that "John Fisher" is, in fact, Jeromy Visser--they have the same perverted misuse of the Enlgish language, with a heavy scatological flourish.
Pearl Jam seems to have written a song that suits Visser to a "T":
"Jeremy"
At home
Drawing pictures
Of mountain tops
With him on top
Lemon yellow sun
Arms raised in a V
Dead lay in pools of maroon below
Daddy didn't give attention
Oh, to the fact that mommy didn't care
King Jeremy the wicked
Oh, ruled his world
Jeremy spoke in class today
Jeremy spoke in class today
Clearly I remember
Pickin' on the boy
Seemed a harmless little fuck
But we unleashed a lion
Gnashed his teeth
And bit the recess lady's breast
How could I forget
He hit me with a surprise left
My jaw left hurting
Dropped wide open
Just like the day
Like the day I heard
Daddy didn't give affection
And the boy was something mommy wouldn't wear
King Jeremy the wicked
Ruled his world
Jeremy spoke in class today
