A perfect gift for young Christmas carolers who want to sing along but can't remember the words. Brightly colored collages provide people, animals, and objects defined clearly enough for counting practice, but artistically enough to present a challenge. Asplind Riley (who illustrated Caroline Crimi's Outside, Inside, 1995, not reviewed) includes a much-needed explanation of the song's origins as a medieval party game, as well as speculation about the real nature of the gifts. The book culminates in two wonderful, gatefold pages showing all the gifts gathered in one long space. A delightful surprise. (Picture book. 3-7)
