This goes with the book, On Halloween Night by Ferida Wolff and Dolores Kozielski, available here from amazon.com.
After every page or every two pages, perform the song below. Add gongs, shakers, whistling wind tubes and thunder drums for a super fun book. If your recorder players are learning E like mine, and pretty solid on BAG they will love to play the "Ooo" part!
Enjoy and Happy Fall!
