Thick As A Brick (Edit #4) lyrics

I've come down from the upper class to mend your rotten ways.
My father was a man-of-power whom everyone obeyed.
So come on all you criminals!
I've got to put you straight just like I did with my old man --
twenty years too late.
Your bread and water's going cold.
Your hair is too short and neat.
I'll judge you all and make damn sure that no-one judges me.
