This tale has been a prize-winning play and a favored production throughout Britain. Originally written for audience participation, it is readily adaptable to nonparticipation format. In this fairy tale, a silver whistle possessing magic powers is lost by a princess, and great adventures are had in the search for it. The whistle may be used to summon the slave of the whistle, who obeys commands, grants wishes and occasionally issues warnings or reproof. Magic, trickery, theft and the intervention of a bird bring about changes in the whistle's ownership. Its uses result in exciting and sometimes awkward situations. Finally, the policeman asks the audience for assistance in his search for the whistle. Their ready help may be accepted and used or skillfully rejected by the actors. The whistle is ultimately returned to the princess, who, along with the policeman, decides how best to deal with it. Simple set with various locales. Fairy tale costumes. Approximate running time: 55 minutes.
