Hi ! I'm Jorge , i tried to do this good, i think that this are the chords that he 
use to perform this music. I'm portuguese, so , sorry about the bad writting. I 
didn't copy anyone.
Capo 4 or 5 or 6. This music works in acoustic and classic guitar.

Enjoy

Me plus you, I'm a tell you one time ( repeat 3x )



G
When I met you girl my heart went knock knock
Cadd9                                           
Now them butterflies in my stomach wont stop stop
G
And even though its a struggle love is all we got
Cadd9
An we gon' keep keep climbin' till the mountain top

G                 Cadd9
Your world is my world
                       G
And my fight is your fight
                   Cadd9
My breath is your breath
And your heart (and now I've got my)
