[Intro]
Am      Dm
[Estrofa]
  Am                         Dm 
I know that your powers of retention  
       Em                     Am 
Are as wet as a warthog's backside. 
                           Dm 
But thick as you are pay attention 
   Em                    Am 
My words are a matter of pride.
[Estrofa]
     Cm                       Am 
It's clear from your vacant expressions, 
    Cm                      Am 
The lights are not all on upstairs. 
    G                           C 
But we're talking kings, and successions, 
     Bm7b5               E7 
Even you can't be caught unawares...
[Estrofa]
       Am                      Dm 
So prepare for the chance of a lifetime, 
      G                     C 
Be prepared for sensational news... 
  Em          Am     Dm         G 
A shining new era is tip-toeing nearer 
       Em          Am 
And where do we feature? 
     Dm        G 
Just listen to teacher.
[Estrofa]
  C  
 
I know it sounds sordid,  
 
    C/Bb  
 
But you'll be rewarded  
 
        A7                 Dm  
 
When at last I am given my dues,  
 
      Bm7b5             E  
 
And injustice, deliciously squared,  
 
Esus E   Am           F  
 
Be   prepared! 
[Medio]
         E7  
 
Yeah, be prepared, heh, heh,   
 
Am  
 
We'll be prepared, heh.   
 
   
 
For what?  
 
Dm  
 
For the death of the king!  
 
     Em  
 
Why, is he sick?  
 
                      Am  
 
No fools, we're gunna kill him...  
 
   
 
And Simba too...  
 
   
 
Great idea, who needs a king?  
 
Dm                            Em  
 
No king, no king, la la la la la la!  
 
                  Am  
 
Idiots! There will be a king!  
 
              Cm  
 
Hey but you said er--  
 
   
 
I will be King!  
 
Am                 Cm  
 
Stick with me, and you'll never go hungry again!  
 
Am  
 
Yay, alright!   
 
G  
 
Yeah,alright!  
 
C  
 
Alright!  
 
   
 
Long live the king,  
 
Bm7b5                    E  
 
Long live the king! 
[Estrofa]
     Am                             Dm 
It's great that we'll soon be connected 
       Em                      Am 
With a king who'll be all time adored. 
                                     Dm 
Of course, quid pro quo, you're expected, 
   Em                     Am 
To take certain duties on board...
[Estrofa]
    Cm                      Am 
The future is littered with prizes 
    Cm                        Am 
And though I'm the main addressee, 
    G            G7        C 
The point that I must emphasize is, 
    Bm7b5                  E 
You Won't get a sniff without me!
[Estribillo]
      Am                       Dm 
So prepare for the coup of the century 
   G                         C 
Be prepared for the murkiest scam 
  Em       Am        Dm       G 
Meticulous planning, tenacity spanning, 
  Em         Am 
Decades of denial 
   Dm         G 
Is simply why I'll  
   C 
Be king undisputed, 
  C/Bb 
respected, saluted, 
    A7                    Dm 
And seen for the wonder I am. 
       Bm7b5                E 
Yes my teeth and ambitions are bared. 
Esus E  Am 
Be   Prepared! 
        Bm7b5                E 
Yes our teeth and ambitions are bared, 
      Am 
Be prepared!
