Intro: Bm   A    G    Gb    Em    Gb G (work out the timing)


Bm              A             G             Gb
I climbed up a mountain, and looked off the edge
Em                     Gb G
At all of the lives that I never have led
Bm                   A              G          Gb
There's one where I stayed with you across the sea
Em                    Gb G
I wonder do you still think of me
Bm           A         G        Gb
I carry your image always in my head
Em                   Gb G
Folded and yellowed and torn at the edge
Bm              A           G        Gb
And I've looked upon it for so many years
Em                 Gb G
Slowly I am losing your face

Chorus

Bm    D               A     E     Bm
Oh the ocean rolls us away, away, away
    D              A    E
The ocean rolls us away


Six's and seven's we live on jet planes
So many faces I don't know the names
So many friends now and none of them mine
Forgotten as soon as we meet
All of these moments are lost in time
Your caught in my head like a thorn on a vine
To forever torment me and I wonder why
Do I wish I'd never known you at all

Chorus x2

Oh the ocean rolls us away, away, away
The ocean rolls us away

(Play verse chords, and then)
Bm             A       G         Gb
The sun and the moon, An ocean of air
Em              Gb G   
So many voices, But nothing is there
Bm             A        G                 Em       G
The ghost of you asking me why, Why did I leave?

Chorus

Oh the ocean rolls us away, away, away

And I lose your hand through the waves 

Song ends on an E chord. Enjoy!
