Since a copy of Olson is archived at Mudcat, the early version of the song is available for them as wants it.
Here is the 1st verse, so that we can list another 'title'.

Sit yo w merry Gentlemen
Let nothing you dismay
For Jesus Christ is borne
to save o r soules from Satan
When as we runne away
O tidings of comfort & joy.

Superscript letters in the Olson text are represented by separation in the two instances in that verse.
