On this date in 1943, Rodgers and Hammerstein's musical Oklahoma! opened on Broadway. Here are some facts you may not know about the show:

- The
musical Oklahoma! is based on a 1931 play called Green
Grow the Lilacs, by Lynn Riggs, a part-Cherokee playwright who
was born in Oklahoma. The play wasn't a massive success, but ten
years later in 1941, Theresa Helburn, a theatre producer, saw its
potential as a musical.
- It
was the first musical written by composer Richard Rodgers and
librettist Oscar Hammerstein II. When Theresa Helburn first
contacted Rodgers about the project, he was working with Lorenz
Hart. Oscar Hammerstein had been keen to set the play to music
before, without any success, and told Rodgers if Hart ever dropped
out, he'd be happy to collaborate instead. As it turned out, Hart
wasn't very interested in the play - he wasn't inspired by the rural
setting, and was in any case unwell. So Hammerstein took over.
- The
musical is set outside town of Claremore, Oklahoma Territory, in
1906. The plot concerns a farm girl named Laurie Williams trying to
make her mind up between two men, cowboy Curly McLain and the
sinister farmhand Jud Fry. There is a sub plot concerning the
romance between cowboy Will Parker and his fiancée, Ado Annie.
- The
title wasn't always Oklahoma! - at first, it was Away We Go!. A
couple of pre-Broadway tryout productions didn't seem promising.
Hammerstein's previous six shows had been flops; there were no
famous people in it and while the audiences liked it, the reviews
were mediocre. Rodgers and Hammerstein had faith in the show,
however and decided to tweak it a little before the Broadway
production. Away We Go! didn't feature the song Oklahoma!, but that
song was added, and the show was re-named for it. It was a Broadway
box-office smash and ran for an unprecedented 2,212 performances.
- Most
of the reviews of the Broadway show were glowing. Only the New York
Post was negative about it. "It all seemed just a trifle too
cute", their critic wrote. She thought the score consisted of
"a flock of Mr. Rodgers's songs that are pleasant enough, but
still manage to sound quite a bit alike ... without much variety in
the presentation," and the show was "very picturesque in a
studied fashion, reminding us that life on a farm is apt to become a
little tiresome."
- Oklahoma!
was the first of a post-war wave of Broadway musicals to reach
London's West End. It opened at the Theatre Royal, Drury Lane on
April 30, 1947 and ran for 1,543 performances. The British
production, too wasn't without its teething troubles. A pre-London
run opened a day late at the Manchester Opera House, after the ship
carrying the cast, scenery, and costumes ran aground on a sandbank
off Southampton.
- Actors
who have appeared in productions of Oklahoma! include Howard Keel,
Hugh Jackman, Alfred Molina, Patty Duke, Margaret Hamilton, Maureen
Lipman and Louise Plowright.
- The
title song became the official state song of the state of Oklahoma
in 1953.
- The
1955 film adaptation featured Shirley Jones in her film debut. It
was directed by Fred Zinnemann and choreographed by Agnes de Mille.
- It
was the first film for which a soundtrack album was produced,
although the first edition didn't feature all the songs. It sold
over a million copies.
