R Kelly - The Worlds Greatest Chords & Tabs

All of the tabs that I looked at for this song are OK, but are all different, and weird chords
are used in some when there is no need. So I’ve done my version, it’s not perfect, but
very close. Please comment/correct this piece, I want to get it perfect, because it is 
an inspiring song, and it feels awesome to play it acoustic.

In the pre-chorus, I wasn’t sure about the Cadd9, a D fits there OK but it fits better
into the chorus, I just couldn’t quite find the perfect chord for it, though the Cadd9
the job

.:Pre-chorus:.

C	Am
  If anybody asks you who I am
       Cadd9
  just stand up tall
                            D
  Look 'em in the face and say

.:Chorus:.

G	                Em7
I'm that star up in the sky
	                   C
I'm that mountain peak up high

Hey I made it
    D
Mmm..

I'm the world's greatest
G                          Em7
And I'm that little bit of hope
                          C
When my backs against the ropes

I can feel it
    D
Mmm..

I'm the world's greatest


Fill:
G, F#, Em, F#

the world greatest,
the world greatest, ever


(repeat the same chord progression)

.:Vers2:.

I Am a giant
I am an eagle ooh..
I Am a lion
Down in the jungle
I am a marching band
I am the people ooh..
I am a helping hand
I Am a hero
Ohh..

(Pre-Chorus)
