Well it can come back now since it’s officially aired.

They’re Pinkie and the Brain,  
Yes Pinkie and the Brain,  
One is a genius  
The other’s insane!
 
They’re pastel colored pones,  
With magic mystic stones,  
They’re dinky,  
They’re Pinkie and the Brain, Brain, Brain, Brain  
Brain, Brain, Brain, Brain,  
Brain!
 
Before the day is done,  
They’ll gather up their girls,  
By the dawning of the sun,  
The Six will save the world!
 
They’re Pinkie and the Brain,  
Yes Pinkie and the Brain,  
With Twilight’s campaign,  
All friendship will regain!
 
They’ll prove their horsey worth,  
Through Ponyville’s rebirth!  
It’s Twinky,  
It’s Pinkie and the Brain, Brain, Brain, Brain,  
Brain, Brain, Brain, Brain,  
PONK!!!

There’s no English audio other than the hack which is not allowed.

Why the original got removed? I remember the original English dialogue was here too.

Why bother, just wait a while and it’ll be handed to you.

They’re Pinkie and The Princess  
Yes, Pinkie and The Princess  
One is a nerd  
The other’s a raver  
They’re ponies from Equestria  
Their colours are strange  
They’re kinky  
They’re Pinkie and The Princess, Princess… (x8)
 
Before Luna raises the moon  
Their plan will be unfurled  
By Celestia’s awakening  
They’ll take over the world.
 
They’re Pinkie and The Princess  
Yes, Pinkie and The Princess  
Their twilight sparkles  
These lyrics are aweless  
To prove their horsey worth  
They’ll overthrow the Earth
 
They’re kinky  
They’re Pinkie and The Princess, Princess (x6)  
Narf!

PERFECT

The editing for this is perfect.
