If you are interested in performing in musical theatre, the apparent fact that ALW has decided not to run a reality talent show for a child to play Dorothy does not mean that this is the end of the road. ALW and the many theatre associate music production companies do still hold auditions for parts as and when they become available. The main Newspaper for advertising comes out every week on a Thursday and is called The Stage. If you register with an online company to do auditions you can be charged for the service. So the best option is the cost of a newspaper as all auditions after that are charged at the discretion of the organiser. The majority of auditions for child roles are free. Best of luck.
