These are lyrics to the Fall version of the song courtesy of Arjan Plug. The Etienne version that I've heard has some minor variations, but it isn't in any way official, so we'll stick to these for now!
Pop-Stock, mix my pop-stock. /
Pop-Stock, mix my pop-stock. /
Pop-Stock, mix my pop-Stock. /
We like pop-stick stickers, /
we like weak TV. /
We like the chocolate animals; /
we eat poor little piggies. /
Pop-stock, mix my pop-stock. /
Pop-stock, mix my pop-stock. /
Pop-stock, try my pop-stock. /
Pop-stock, buy my pop-stock. /
Now all the bourgeoisie, /
they hate our crazy scene /
'cause we dig pop [...] stickers /
and we like weak TV. /
But the pop-stock sale assistants /
are beyond their control. /
They stayed at school /
and tolerate bad manners. /
Pop-stock, mix my pop-stock. /
Pop-stock, mix my pop-stock. /
Pop-stock, try my pop-stock. /
Pop-stock, buy my pop-stock. /
Now come on kids, /
let's get this thing together. /
Let's get this thing together /
and make it bad. /
We don't need this three chords /
and big boots and cosmic trash... / uh... /
He's bust his guitar! /
Let's get this thing together. /
Forget Lee Cooper! /
Let's get this thing together. /
Why are you smiling? /
Why are you laughing /
At or with this song? /
It's not like your scene, your scene. /
Pop-stock, mix my pop-stock. /
Pop-stock, mix my pop-stock. /
Pop-stock, try my pop-stock. /
Pop-stock, buy my pop-stock. /
