O Come Little Children (or the Up-Down Song)

This song, devised by Sharron Beamer, reminds the children of the correct bowing. The words up and down coincide with the bow moving up or down.

Up down then down up is the right way to go.
Up down once a-gain then we make the bow slow.
Up down is quite hard but I think I can do.
Up bows every time in the right place like you...
