This probably isn't how he plays it, but it sounds good. Try capo-ing on different frets 
find the best key for your voice. Here's what I got:

We Fall Down

Verse 1:

G                D        Em           C       D
We fall down, we lay our crown at the feet of Jesus
G                     D         Em           C       D
The greatness of His mercy and love at the feet of Jesus


Chorus:

        C     G    D
We cry Holy, Holy, Holy
        C     G     D
We cry Holy, Holy, Holy
        C     G     D           G
We cry Holy, Holy, Holy is the Lamb


Verse 2:

G                      D         Em            C     
 D
No more fears, You've dried our tears at the feet of Jesus
G                D           Em        C       D
Grace abounds to all who've found the feet of Jesus


Chorus


Thats about it. Have fun. To God be the Glory!
