The Perfect Nanny, as sung by Jane and Michael. If you want this choice position, you must have a cheerful disposition. Rosy cheeks, no warts, play games, all sorts. You must be kind, you must be witty. Very sweet and very pretty. Teach us tricks, give us treats. Sing songs, bring sweets. Never be cross or cruel, never feed us castor oil or gruel. Love us as a son and daughter. And never, never smell of barley water. If you won't scold and dominate us, we will never give you cause to hate us. We won't hide your spectacles so you can't see. Put frogs in your bed or pepper in your tea. Hurry, Nanny, many thanks. Sincerely, Jane and Michael Banks.
