My own arrangement has three verses: one with a simple arpeggiated bass, one with altered rhythm and meter, and one that is partially set in a canon. If you try to sing along the words you will find that my technique for avoiding boring was actually to mutilate the traditional structure. I don't repeat the phrase before the chorus. Each verse is quite a bit shorter than it would have to be if it were sung.
Below is a typical English scene, except for the fact that it's technically in Scotland. This was the park around the block from where we used to live, with a view of the parish church just across the hedge. I have no doubt that "The First Noel" has been sung there many, many times.
