If the boys are dancing like this you have the wrong music on. It's probably too fast and too complicated.
Give them all a feather and let them blow the feather or bat it with their hands to keep it up, or use teddy bears to do appropriate stroking, or get them to be trees (roots are legs and can't move) so it is just a hand dance. Or get them all to sit in a circle and use their hands to pretend to be sea creatures. Pick pieces that are more gentle, provide some structure and they will calm down.
