Publisher Desc.  Just One is just one perfect musical. Mordecai encourages Esther with the toe-tapping number What Do You Do? (when you get knocked down? You get back up!), the evil Haman sings Have You Ever Had A Thorn In The Flesh?, and Esther inspires with the titular song Just One. Do Not miss this! This musical is in 2 Acts and 13 Scenes, with 4 main characters and an interesting array of cast members.
