I play it as a tune in standard tuning: chords are (find you own extra notes with little finger/whatever):Am C G(B) Am/G(B) C Am F Em7 Am D D(C) G/D D Am/C G(B) Am/G(B) Am
C C G(B) Am F Em7 Am Am
...or something like that. S'funny how the muscle memory doesn't work so well without the guitar in my hands...
Happy Christmas!
