The original song is called Particle Man and was created by They Might Be Giants. Sanzo and his tortured comrades belong to Kazuya Minekura.
Sanzo Man
Sanzo man, Sanzo man
Doing the things a Sanzo can.
What's he smoking? It's not important,
Sanzo man.
Is he a woman or is he a man?
When he's in the rain does he get sad?
Or does the rain get sad instead?
Nobody knows, Sanzo man.
Kappa man, Kappa man,
Kappa man hates Monkey man.
They have a fight, Sanzo wins.
Too bad, man.
Monocle man, Monocle man.
Smarter than the entire universe man.
Usually kind to the stupid men,
Monocle man.
He's got a watch in one of his womanly hands,
A bright chi ball in his other hand.
When it hits the demons they go to happy land.
Powerful man, Monocle man.
Monkey man, Monkey man.
Hit on the head with a paper fan.
Living his life on free handouts,
Monkey man
Is he hyper or does he have ADHD?
Why is he obsessed with yellow?
Who came up with monkey man?
A rock man, Sanzo man
Kappa man, Kappa man
Kappa man hates Sanzo man
They have a fight, Monocle wins
Too bad, man
