I don't remember the details of the song, but you need to be slightly more accurate about the hands -- the hands, with the thumb and finger touching are turned upside down and inward, then laid against the face with the rest of the fingers aligned along the cheek so that they represent both goggles and face mask. This is done in one movement. We began it with: Junior Birdmen, ASSEMBLE!! This was followed by a pterodactyl scream (an almost voiceless howl over the larynx). Then the song would begin.
