The cast features 24 children, the youngest of whom is ``in fairy training'' at age3.

All proceeds will be donated to the Rett Syndrome Australian Research Fund, a charity that helps care for sick children with Rett Syndrome, a debilitating neurological disorder diagnosed almost exclusively in females.

Rett Syndrome leaves its victims profoundly disabled, requiring maximum assistance with every aspect of daily living.

Organiser Daphne MacDonald said the play was for people of all ages. ``It's helping a good cause and we want to get as many people as we can,'' she said.

``It's an exciting tale of turning someone who was very naughty into a good person. It's a good story and has a happy ending.''

Wilma the Witch will be performed on Saturday, December 15, at 2pm, at Campbelltown Town Hall on Queen Street.
