can somebody summarize these plays for me?

Wikipedia isn't good for everything, but it is kick *** at providing synopsis of plays.

Carousel: http://en.wikipedia.org/wiki/Carousel_%28musical%2...

Annie Get Your Gun: http://en.wikipedia.org/wiki/Annie_Get_Your_Gun_%2...

Charlie Brown: http://en.wikipedia.org/wiki/You%27re_A_Good_Man_C...

The Music Man: http://en.wikipedia.org/wiki/You%27re_A_Good_Man_C...

Oklahoma: http://en.wikipedia.org/wiki/Oklahoma%21

With the exception of YAGM,CB these aren't really children's musicals, per se. Are you looking to direct something?

Oklahoma is about a guy named Curly who fals in love with a girl named Laurey, but Laurie's hired haned, Jud Fry, also likes Laurey, and Laurey likes Curly but she's too stubborn to admit it, and then things happen and in the end, Curly and Laurey get married. I was just in that production with 6-10th graders, and it was really fun.

The music man is about a person who comes to town and tries to start a band with kids in it and gets money from people and tries to leave town. Then he falls in love with the librarian, who knew that he was a scammer but still liked him. It's a great play, and it has been done with younger kids. You can look into the Junior version of it.

I've seen Carousel and You're a good man, Charlie Brown, but I can't remember enough to tell you what they are about. They were both great plays though.

You can look online for other summaries of the plays that I didn't know.

Hope that helps!

Music man. - Charlie comes to town. Undesirable. Wants to hook up with Marion. Marion, the librarian, thinks he is unsuitable but eventually gives in.

Oklahoma - All about a farm community going to the fair and al the boys competing for all the girls.
