Context paragraphs:
The King and I (1956 film): The King and I is a 1956 American musical film made by 20th Century Fox, directed by Walter Lang and produced by Charles Brackett and Darryl F. Zanuck.  The screenplay by Ernest Lehman is based on the Richard Rodgers and Oscar Hammerstein II musical "The King and I", based in turn on the novel "Anna and the King of Siam" by Margaret Landon.  That novel in turn was based on memoirs written by Anna Leonowens, who became school teacher to the children of King Mongkut of Siam in the early 1860s.  Leonowens' stories were autobiographical, although various elements of them have been called into question.  The film stars Deborah Kerr and Yul Brynner.

Margaret Landon: Margaret Landon (September 7, 1903 – December 4, 1993) was an American writer best remembered for "Anna and the King of Siam", her best-selling 1944 novel of the life of Anna Leonowens which eventually sold over a million copies and was translated into more than twenty languages.  In 1950, Landon sold the musical play rights to Richard Rodgers and Oscar Hammerstein II, who created the musical "The King and I" from her book.  A later work, "Never Dies the Dream", appeared in 1949.

In Praise of Limestone: "In Praise of Limestone" is a poem written by W. H. Auden in Italy in May 1948.  Central to his canon and one of Auden's finest poems, it has been the subject of diverse scholarly interpretations.  Auden's limestone landscape has been interpreted as an allegory of Mediterranean civilization and of the human body.  The poem, "sui generis", is not easily classified.  As a topographical poem, it describes a landscape and infuses it with meaning.  It has been called the "first … postmodern pastoral".  In a letter, Auden wrote of limestone and the poem's theme that "that rock creates the only human landscape."

Anna and the King of Siam (film): Anna and the King of Siam is a 1946 drama film directed by John Cromwell.  An adaptation of the 1944 novel of the same name by Margaret Landon, it was based on the fictionalized diaries of Anna Leonowens, an Anglo-Indian woman who claimed to be British and became governess in the Royal Court of Siam (now modern Thailand) during the 1860s.  Darryl F. Zanuck read Landon's book in galleys and immediately bought the film rights.

W. H. Auden: Wystan Hugh Auden ( ; 21 February 1907 – 29 September 1973) was an English-American poet.  Auden's poetry was noted for its stylistic and technical achievement, its engagement with politics, morals, love, and religion, and its variety in tone, form and content.  He is best known for love poems such as "Funeral Blues", poems on political and social themes such as "September 1, 1939" and "The Shield of Achilles", poems on cultural and psychological themes such as "The Age of Anxiety", and poems on religious themes such as "For the Time Being" and "Horae Canonicae."

Epilogue For W. H. Auden: "Epilogue For W. H. Auden" is a 76-line poem by Louis MacNeice.  It was written in late 1936 and was first published in book form in "Letters from Iceland", a travel book in prose and verse by W. H. Auden and Louis MacNeice (1937).  MacNeice subsequently included it as the last poem in his poetry collection "The Earth Compels" (1938).  "Epilogue For W. H. Auden" reviews the Iceland trip MacNeice and Auden had taken together in the summer of 1936; the poem mentions events that had occurred while MacNeice and Auden were in Iceland, such as the fall of Seville (marking the start of the Spanish Civil War) and the Olympic Games in Berlin.

The King and I: The King and I is the fifth musical by the team of composer Richard Rodgers and dramatist Oscar Hammerstein II.  It is based on Margaret Landon's novel, "Anna and the King of Siam" (1944), which is in turn derived from the memoirs of Anna Leonowens, governess to the children of King Mongkut of Siam in the early 1860s.  The musical's plot relates the experiences of Anna, a British schoolteacher hired as part of the King's drive to modernize his country.  The relationship between the King and Anna is marked by conflict through much of the piece, as well as by a love to which neither can admit.  The musical premiered on March 29, 1951, at Broadway's St. James Theatre.  It ran for nearly three years, making it the fourth longest-running Broadway musical in history at the time, and has had many tours and revivals.

He is the literary executor of the Estate of W. H. Auden and the author or editor of several books about Auden's work, including "Early Auden" (1981) and "Later Auden" (1999).  He is also the author of "The Things That Matter: What Seven Classic Novels Have to Say About the Stages of Life" (2006). , about nineteenth- and twentieth-century novels, and "Moral Agents: Eight Twentieth-Century American Writers" (2015).

Anna and the King of Siam (novel): Anna and the King is a 1944 semi-fictionalized biographical novel by Margaret Landon.

Refugee Blues: "Refugee Blues" is a poem by W. H. Auden, written in 1939, one of a number of poems Auden wrote in the mid- to late-1930s in blues and other popular metres, for example the meter he used in his love poem "Calypso," written around the same time.  The poem dramatizes the condition of Jewish refugees from Nazi Germany in the years before World War II, especially the indifference and antagonism they faced when seeking asylum in the democracies of the period.  In some later editions of Auden's poetry, the poem is not identified by name but is the first of ten poems grouped together in "Ten Songs," which also includes the above-mentioned "Calypso."
