Did you ever go to Ozfest in Liberal? My aunt used to play Glinda and when my cousin was younger, she would play Dorothy. I'm actually related to Billie Burke (the woman who played Glinda in the movie). She's like a great-great Aunt or something.
Random piece of off-topic trivia, did you know that she was completely bald when she shot WOZ? Due to the quality hair dye in those days and how much she colored her hair, it all fell out LOL.
