Here is an ABC encoding of Silent Night found using John Chambers' tune finder. He uses ABC chord notation (i.e., [ … ]) to get harmony and uses guitar chord notation as well. The meter switches between 3/4 and 2/4. I see other versions are encoded using 6/8. It's also available in a number of other keys. I chose one in C because that was Sheila's preferred key.
