The song is in F minor, but has been transposed here to A minor for piano simplicity. 

             C
I was just a boy
                   Am
My father seemed a mountain then
       C                          F
With a voice that could shake the seas
            C                     Am
My mother's ghost hung across his shoulders
       E                                F
And he said she was still watching over me


               C
My brother was home
                 Am
Just returned on army leave
         C                      F
Told his stories with a distant stare
          C
And as it snowed
                     Am
The wind was howling through the trees
      E                   F                C
And I spent my night just listening by the fire

C, Am, Em, F, C, Am, E, F, E, Em, E, Em

   Em                             F
My hands move the creases from my brow
          C
Soft as a breath
            G
It's like a feather
  Em                             F
I dreamed of a lonely voice that night
         C
Quiet as death
           G
Outside my window
          Em             F
It sang a sad and lovely tune
           C
Clear as a bell
          G
Soft as a shiver
         Em                 F
It said, I want you all the time
   Fm                       C
It said, I want you all the time

C, Em, C, Em, C, Em, C, Em

            C              Em
Goodbye bad thoughts
                 C         Em
I'm safe under covers 
               C           Em
So goodbye bad thoughts
                      C    Em
'Cause I'm safe under covers
                  C
Now I can see you again
