I don't mean this to be offensive, really. Im just curious, what kind of ensemble roles are there for children in the Sound of Music? (or is it an all youth production?, in which case of course there are ensemble roles). Congratulations to your daughter! I'm sure she will have a fantastic time, SOM is a great show.
p.s. So are you J's mom, or A's mom....? lol...you must have another daughter.
