Since there is barely any guitar in the entirety of this song (if you listen
very closely at the end you'll hear it deep in the background), this is
obviously an adaptation.  To my ear, it works pretty well.  Your mileage may
vary.

Capo 3

Verse picking pattern (mirrors piano part):
   C    Am   C

To add a little fullness to the song, you should throw in some other notes and
strum from time to time.
