I got a request for this, so I decided I was up to the challenge. 
I hope this sounds good.  Clapton seems to like the key of E. 
Have fun, and good luck! 
 
Lyrics 
 
INTRO: 
 
There is another guitar here that I haven't tabbed, but you can figure that one out. 
I think these two parts are actually two different guitars, but I'm not sure.

This is the basic part behind the verse:

   E       A     E                     E       A   E

Here's the chorus.  There isn't much guitar, so just strum this: 
 
          F#m    G#     C#m 
That I can    change the world 
F#m           G#               C#m 
I will be the sunlight in your universe 
F#m               G#              C#m    Cm    Bm 
You will think my love was really some - thing good 
     A    E     G#m Gm F#m 
Baby if I could cha - nge the world 
 
Clapton does this after the chorus: 
 
   E       A       E                 E              A              E 
   +   +   +   +       +  +  +  +    +     +        +     +        +   +       +       +

A:-------------------|-------------|----------------------------|------2h4-----0h2-0h2-0h2----| 
E:-------------------|-------------|----------------------------|-----------------------------| 
 
He continues into another verse, and plays the same as the last verse 
 
Then a chorus, which has a bit added to the end: 
 
That I can change the world 
I will be the sunlight in your universe 
You will think my love was really something good 
     A    C#m   Bm Bbm A      E 
Baby if I could cha - nge the world 
     A    C#m   Bm Bbm A 
Baby if I could cha - nge the world

LYRICS: 
 
If I could reach the stars I'd pull one down for you 
Shine it on my heart so you could see the truth 
That this love I have inside is everything it seems 
But for now I find it's only in my dreams 
 
 
CHORUS 
That I can change the world 
I would be the sunlight in your universe 
You will think my love was really something good 
Baby if I could change the world 
 
 
If I could be king even for a day 
I'd take you as my queen I'd have it no other way 
And our love will rule in this kingdom we have made 
Till then I'd be a fool wishin' for the day 
 
 
CHORUS 
That I can change the world 
I would be the sunlight in your universe 
You will think my love was really something good 
Baby if I could change the world 
Baby if I could change the world
