They play this with CAPO 5, but its a bit high for me so I take it down to 4, but it's your choice.
Intro: G Am Em Em (x2)
G Em C
I heard the bells on Christmas Day
G D Am
Their old, familiar carols play,
Em G
and wild and sweet
Am Em
The words repeat
C D G
Of peace on earth, good-will....to men!
G Am Em Em (x2)
G Em C
Till ringing, singing on its way,
G D Am
The world revolved from night to day,
Em G
A voice, a chime,
Am Em
A chant sublime
C D G
Of peace on earth, good-will....to men!
G Am Em Em (x4)
G D C
And in despair I bowed my head;
G D Am
"There is no peace on earth," I said;
Em G
"For hate is strong,
Am Em
And mocks the song
C D G
Of peace on earth, good-will....to men!"
G Am Em Em (x2) OR Just G
G D C
Then pealed the bells more loud and deep:
G D Am
"God is not dead, And not asleep;
Em G
The Wrong shall fail,
Am Em
The Right prevail,
C D G
With Peace on earth, good-will to men
G Am Em Em
Peace on earth, good-will to men [x3]
C D G
Peace on earth, good-will to men
