Verse:

C#m       B             A
I love you in the light, I love you in the dark
    C#m                   B
and my mind has been made up
        A
because you threw the sparks
that set my heart on fire
C#m    B             A
         and now the stars are falling from the sky
         C#m  B     A                              B
they're on fire and fall straight into your eyes (your eyes)

Chorus:

     E          B              A
I am Invincible,oh, as long as I'm in love with you
B    C#m        B            A
I am Invincible,oh, there is nothing we cannot do


Verse:

C#m     B            A
Missing you everyday-it's not enough for me
C#m          B                  A
we make it so hard for ourselves so easily
        C#m                    B
and it's funny how the one thing that makes me crazy
       A
is the same that keeps me sane
C#m        B             A                      C#m    B
my minds a million miles away, but nothing ever changes
A
no never change


Chorus:

     E          B              A
I am Invincible,oh, as long as I'm in love with you
B    C#m        B            A
I am Invincible,oh, there is nothing we cannot do


C#m              B    A
   Your arms are my home,
C#m                 B      A     E
and I've been homesick for oh so long
   A             B  C#m
So bring me back home,
A                        B  C#m   
back where I, back where I belong

I am Invincible,  Oh, I am Invincible
