The song is down a half step.

Verse 1#

D                 A
You're looking so beautiful
                Bm
standing in the light
                     G
I've waited for this night

for my whole life
D                    A
I reach to grab your hand
               Bm
I take it into mine
                  G
Our hearts become numb

Our hearts have become one
Bm                 G
And I'll wait for you
       D
If our worlds falling down
    A 
cumbling to the ground
Bm                 D
And I'll wait for you
       G
If our worlds falling down
     A
crumbling to the ground

Chorus 1#

D         A
With this honor
Bm
On weak knees I stand
             G
strengthened by your hands

Verse 2#

As the music starts to play
that look upon your face
I see whats in your eyes,
you see whats inside mine
We see our life together
we feel it as we dance
Theres rhythm in our love
its rhythm from above
And Ill wait for you
If our worlds falling down
crumbling to the ground
And Ill wait for you
If our worlds falling down
crumbling to the ground

Chorus 2#

With this honor
On weak knees I stand
strengthened by your hands

Verse 3#

Bm                        G
With this dance our life begins
           D                 A
With these steps love has no end
Bm                        D
With this dance our life begins
G                     A
And Ill wait, and Ill wait

Chorus 3#

With this honor
On weak knees I stand
strengthened by your hands
