[Callers] How to teach various steps to beginners?

Hi. I just called my first contra dance at camp last week. I didn't die, so I'm thinking of working with our son's nature class to do some family dances. In the meantime, I will try to call a contra when I can as a guest at our local dances. Do you know of a source/s (would you share yours) that has good clear wording for how to teach things like Hey, Pull-by, California Twirl, Petronella, Rory O'more, etc? I will ask good callers if I can record their teachings when I'm at dances with lots of beginners..... Where else can I learn good, simple wording? I sure don't want to reinvent it myself...... Thanks! claire takemori
