It's pretty easy. Just listen to the song for the strumming pattern.
C
C
I laid you down
F G
In a wooden box with lonesome thoughts
C
Down in the graveyard.
You came round
Inside the pitch black of your coffin
In the ground.
[ Tab from: https://www.guitartabs.cc/tabs/c/chad_vangaalen/graveyard_crd.html ]
You let your ghost
Leak through the earth above your grave
And coast around
To find your love
That you left behind inside
of this old town
Who are you?
Who are you?
So come on down
Come and walk around and
Through the graveyard
Come on by
Come and slip and slide right
Through the ground
You'll be close
Back to your coffin in the ground
Out by the sound
Of your lover
Who's been buried right beside you
In the ground
Who are you?
Who are you?
