I'm trying to recall all the words for a song I learned in school about the three kings. It was set to a tune which I now know is 13th C Provencal, and it went:

Late at night, upon a great highway
I saw three kings of the East come riding.
In the sky there shone a bright array
to guide these kings upon their eager way.
While noble courtiers went on before
ta tum tum tum tum etc
dispelling dangers that hovered near.

If anybody knows the missing lines or any other verses, I would like to have them by January 1 for our jam.

I have tried Google and the Digitrad with no results.
