Is this your first production with this group of kids? If yes.. then as Scuttle would answer "It's hard to say". If no.. then I would think that you have a sense already as to how big your potential audience is. "Honk! Jr." is a great show, and although some may think it lacks "name appeal" .. word of mouth would certainly apply. For our troupe here, "Honk! Jr." was our first "Jr" production ever, so we limited ourselves to two performances. If I were to do it today (5 yrs later).. I would be doing three. One option for getting the word of mouth going, is to invite Girl Guides and/or Cub Scouts to visit some of your rehearsals. Give them a tour..talk about the roles within the theatre.. and then show them some of the upcoming show in rehearsal. It is certain to get some heads turning. "Cool" Lastly.. don't forget to post pictures when you are done!!
