I'm pretty sure the Intro is Just a progression of G - F#7 - Bm

But I'm not sure about this, just improvise.

D                 Bm
Stick and stones, a few clam living bones
G                      Bm
Salt and water melt my skin
D                       Bm
If you don't set sail, you'll end up in the belly of a whale
G                               Bm
No swallow saint will mock your grave

G                     Bm
Every light of every day
G                Bm
It's a way into decay
            G     F#7     Bm
But I won't cry myself to sleep
            G      F#7    Bm
'Cause my soul no longer weeps
       G                 F#7         Bm
But my body lies in the heart of the sea

Darkness breaks and we heard the morning wakes
She marks us weary as we drown
Show no remorse as you will make a beautiful course
Let's do the one you love the most

Every light of every day
It's a way into decay

Don't fornicate
With the one you love to hate
You'll wind up dead before she vows

But I won't cry myself to sleep
'Cause my soul no longer weeps
While my body lies in the heart of the sea

G         F#7     Bm
Another useless confrontation
G         F#7     Bm
Leaves any A-class confirmation
G            F#7
Now the end appears
Bm                          
And my eyes are filled with fear

Bm
I am blind, I am blind, take me up before I die
             G               F#7        Bm
Don't wanna end up in the heart of the sea
Bm
Oh, I am blind, I am blind, take me up before I die
            G               F#7        Bm
I don't wanna end up in the heart of the sea

Now the lesson is lesson is learnt
Don't you remember the fire from your burns
Walk, it's better even truly feel

But I won't cry myself to sleep
'Cause my soul no longer weeps
While my body lies in the heart

But I won't cry myself to sleep
'Cause my soul no longer weeps
While my body lies in the heart of the sea
Heart of the sea
