This song is on Dan's 1999 album "First Christmas Morning."

Here is a clip from the recording, with a couple of verses and an instrumental break.   

Here are Dan's notes about this song from his website:

AT CHRISTMAS TIME:
("This is one of mine and the last piece I wrote for the project specifically to use as an opening number. I wanted to write a joyous, rollicking song that employed male and female voices answering each other and had an 1800's feel of repetitive couplets.")
