The noble Duke of York,
He had ten thousand men. (Hold up ten fingers.)
He marched them up the hill, (March on tip-toes in place.)
And then he marched them down again. (March down until squatting.)
And when you're up you're up. (March tall again.)
And when you're down, you're down. (March to squat.)
And when you're only half way up, (in half-way position)
You're neither up (Stretch tall.) nor down. (Squat down.)
