Yes, I have some plays that deal with weddings: All For Love,
the final scene of Under Siege, and I can think of others if
I try.
In America our favorite plot, sort of our National plot, has
always been a boy and girl from different backgrounds-- esp.
religious backgrounds--- falling in love and getting together
to marry and their reluctant families coming to accept that
we are all Americans, all had immigrants somewhere in the background.
"Abie's Irish Rose" was a very popular play on this
subject 100 years ago. "Oklahoma", 60 years ago, gets
farmers and cowboys together.
I just saw a reading of a new play in NYC where the heroine's
family is from India and they are looking for a nice boy of
similar background for her to marry--- because her horoscope
says that if she doesn't marry by age 26 she will never marry.
They are all frantically arranging dates and husband prospects
for her, when the girl realizes that she loves the American
boy who has been her best friend since high school. Her parents
never thought of him-- they believed that he was gay! By the
end of the play, which is very funny, the parents admit that
the astrologer said "never marry an Indian", not "never
marry", and the young man is trying very hard to convince
her family that he will make a good husband.
I loved this play, because it was full of tolerance and kindness
and hope. Somewhere in my files I have the name of the play
and the author-- Mrinalini Something-- I will send this to you
when I find it.
