"The First Noel" is a traditional Christmas carol. Track 3 of the album Arthur's Perfect Christmas, it is one of several such carols performed by D.W., however, D.W. does not sing the songs correctly. She instead sings her own entirely made up lyrics to the tunes of the original songs.
I, D.W. Read, will now sing some Christmas carols.
The first Noel, the second Noel
The third Noel, the fourth Noel
If you need more than that
Get somebody else
'Cause I can't count higher than four Noels.
