Madame Butterfly: A Tragedy of Japan is a play in one act by David Belasco adapted from John Luther Long's 1898 short story "Madame Butterfly".
 It premiered on March 5, 1900, at the Herald Square Theatre in New York City and became one of Belasco's most famous works.
 The play and Long's short story served as the basis for the libretto of Puccini's 1904 opera, "Madama Butterfly".
 The title role was originally played in New York and London by Blanche Bates; in 1900–01 in New York by Valerie Bergere; and in 1913 by Clara Blandick.
Emilio Venturini (1878 - 1952) was an Italian operatic lyric tenor known for his portrayal of character roles.
 He made his professional opera debut in 1900 in Italy where he remained for the next several years.
 In 1901 he sang the role of Brighella in Mascagni's "Le maschere" at the Teatro Regio in Turin.
 He made his La Scala debut in 1903 as Froh in Wagner's "Das Rheingold" and sang in the premiere of Umberto Giordano's "Siberia".
 In 1904, he originated the role of Prince Yamadori in Puccini's "Madama Butterfly" at La Scala.
 In 1905, Venturini joined the roster of the Opéra National de Paris.
 In 1907 he moved to London to sing with Royal Opera at Covent Garden.
 In 1910, Venturini became a member of the Chicago Opera Association where he performed roles until the summer of 1917.
 While in Chicago he sang mostly character parts but did sing some major roles like Turiddu in "Cavalleria rusticana", Edgardo in "Lucia di Lammermoor" and the Pinkerton in "Madama Butterfly".
 In 1911 he sang the roles of Cassio in Verdi's "Otello" and Spoletta in Puccini's "Tosca" at the Metropolitan Opera.
 Venturini also returned to Italy for brief periods in 1910, 1911, and 1916 to perform roles with the Teatro Massimo in Palermo.
 In 1921, Venturini joined the roster at La Scala and sang roles with that opera house until 1948.
 He notably originated the roles of Il Tempiere in Boito's "Nerone" in 1924 and Pang in Puccini's "Turandot" in 1926.
 and was the first to record the role of Nereo in Boito's "Mefistofele" in the 1931 La Scala recording.
Riders to the Sea is a short one-act opera by Ralph Vaughan Williams, based on the play of the same name by John Millington Synge.
 The composer completed the score in 1927, but it was not premiered until 1 December 1937, at the Royal College of Music, London.
 The opera remained largely the province of students and amateurs until it entered the repertoire of Sadler's Wells in 1953.
"The Dancing Girl" (舞姫 , Maihime ) was the first published short story by the Japanese writer Mori Ōgai.
 The story first appeared in "Kokumin no Tomo" (People's Friend, 国民之友) in 1890, and is based on Mori's own experiences as a medical student in Germany.
 In some ways, this tale foreshadows Puccini's "Madama Butterfly", which deals with a similar theme but with a slight role reversal: in "Madama Butterfly", a Western man abandons a Japanese woman, while in "The Dancing Girl" a Japanese man leaves a Western woman.
