In many French-speaking countries and regions Epiphany (a post-Christmas feast day on Jan. 6 that celebrates the three Magi (Kings) seeing Jesus for the first time) is celebrated with a "King Cake." This is typical for Mardi Gras celebrants in Louisiana as well as countries around the world.
This traditional French children's song for Epiphany is sung to me by my grandchildren about 642 times when I visit them in Brussels (the French-speaking part of Belgium). The traditional Galette des Rois ("Kings Cake" - a round, flat pastry similar to a tart or thick pancake) has a tiny statue of a king (originally a baby Jesus, or now any trinket) baked inside. The child who gets the piece with the king is the "king for the day." Sometimes a large fava bean is substituted (easier on the teeth!).

This song and tradition are sure to turn the memories of a Christmas gone by into a fun way to bring in a new year!
