On Old MacDonald's farm there lived a pig with a wonderful voice. Animals came from miles around just to hear Percival sing; and so did Hiram J. Potter who bought him and took him to London for a career in Grand Opera. But Percival wasn't keen on London so he devised a scheme to get home to the farm. This play offers parts not only for the farm animals, but the scenery ordered by the stage manager has unaccountably failed to turn up, so some actors have to represent a house, trees and so on!Flexible casting
