In your vast resources, have you come upon an African story about a father, whose sons are threatened by the local bad witch? He hides them in a treehouse and then disguises himself to face the woman, only armed with his magic drum. Of course, I can't find this tale in any of my books or the Internet and I'm pulling my hair out, trying to remember where I've read or heard it in the last year. Argh! Can you help me?
