Old MacDonald Had a Farm

There are only two pull tabs in this musical pop-up bookone that sets a computer chip humming the electronic version of the well-known song, and another that gets Old MacDonald dancing. The rest of the book is devoted to lyrics and the unfolding of a fence along which all of the barnyard animals cavort. The illustrations are a bright and playful accompaniment to a song that has long been a favorite with children; the only warning to parents might be to teach young ones how to turn it off as well as on.
