Oedipus (US  /ˈɛdɨpəs/ or UK /ˈiːdɨpəs/; Ancient Greek: Οἰδίπους Oidípous meaning "swollen foot") was a mythical Greek king of Thebes. He fulfilled a prophecy that said he would kill his father and marry his mother, and thus brought disaster on his city and family. This legend has been retold in many versions, and was used by Sigmund Freud to name the Oedipus complex.

There are many different versions of the legend of Oedipus due to its oral tradition. Significant variations on the legend of Oedipus are mentioned in fragments by several ancient Greek poets including Homer, Hesiod, Pindar, Aeschylus and Euripides. However, the most popular version of the legend comes from the set of Theban plays by Sophocles: Oedipus the King, Oedipus at Colonus, and Antigone.

Oedipus was the son of Laius and Jocasta, king and queen of Thebes.

After having been married some time without children, Laius consulted the Oracle of Apollo at Delphi. The Oracle prophesied that any son born to Laius would kill him. In an attempt to prevent this prophecy's fulfillment, when Jocasta indeed bore a son, Laius had his ankles pinned together so that he could not crawl; Jocasta then gave the boy to a servant to abandon ("expose") on the nearby mountain. However, rather than leave the child to die of exposure, as Laius intended, the sympathetic servant passed the baby onto a shepherd from Corinth and then to another shepherd.

Regina Ilyinichna Spektor (Russian: Реги́нa Ильи́нична Спе́ктор, IPA: [rʲɪˈɡʲinə ˈspʲɛktər], English: /rɨˈdʒiːnə ˈspɛktər/; born February 18, 1980) is an American singer-songwriter and pianist. Her music is associated with the anti-folk scene centered in New York City's East Village.

Spektor was born in Moscow, Soviet Union in 1980 to a musical Russian Jewish family. Her father, Ilya Spektor, is a photographer and amateur violinist. Her mother, Bella Spektor, was a music professor in a Soviet college of music and now teaches at a public elementary school in Mount Vernon, New York. She has a brother Barry (Bear), who was featured in track 7, "* * *", or "Whisper", of her 2004 album, Soviet Kitsch.

She learned how to play piano by practising on a Petrof upright that was given to her mother by her grandfather. She was also exposed to the music of rock and roll bands such as The Beatles, Queen, and The Moody Blues by her father, who obtained such recordings in Eastern Europe and traded cassettes with friends in the Soviet Union. The family left the Soviet Union in 1989, when Regina was nine and a half, during the period of Perestroika, when Soviet citizens were permitted to emigrate. Regina had to leave her piano behind. The seriousness of her piano studies led her parents to consider not leaving the USSR, but they finally decided to emigrate, due to the ethnic and political discrimination that Jews faced. Spektor is fluent in Russian and reads Hebrew, and has since paid tribute to her Russian heritage, quoting the poem February by the Russian poet Boris Pasternak in her song Après Moi, and stating “I’m very connected to the language and the culture.”

In a career that spans seven decades and includes substantial roles in each of the dramatic arts, Plummer is probably best known to audiences as the autocratic widower Captain Georg Ludwig von Trapp in the hit 1965 musical film The Sound of Music alongside Julie Andrews. Plummer has also ventured into various television projects, including the legendary miniseries The Thorn Birds.

His most recent film roles include the The Insider as Mike Wallace, the Disney-Pixar 2009 film Up as Charles Muntz, the Shane Acker production 9 as 1, The Last Station as Leo Tolstoy, The Imaginarium of Doctor Parnassus as Doctor Parnassus, The Girl with the Dragon Tattoo as Henrik Vanger, and Beginners as Hal.

Thomas Andrew Lehrer (born April 9, 1928) is an American singer-songwriter, satirist, pianist, and mathematician. He has lectured on mathematics and musical theater. Lehrer is best known for the pithy, humorous songs he recorded in the 1950s and 1960s.

His work often parodies popular song forms, though Lehrer usually creates original melodies when doing so. A notable exception is his song "The Elements", where he sets the names of the chemical elements to the tune of the "Major-General's Song" from Gilbert and Sullivan's Pirates of Penzance. Lehrer's earlier work typically dealt with non-topical subject matter and was noted for its black humor, seen in songs such as "Poisoning Pigeons in the Park". In the 1960s, he produced a number of songs dealing with social and political issues of the day, particularly when he wrote for the U.S. version of the television show That Was The Week That Was.

In the early 1970s, he retired from public performances to devote his time to teaching mathematics and music theatre at the University of California, Santa Cruz. He did two additional performances in 1998 at a London gala show celebrating the career of impresario Cameron Mackintosh.

Carl Orff ((1895-07-10)July 10, 1895 – March 29, 1982(1982-03-29)) was a 20th-century German composer, best known for his cantata Carmina Burana (1937). In addition to his career as a composer, Orff developed an influential method of music education for children.

Orff was born in Munich on July 10, 1895. His family was Bavarian and was active in the Army of the German Empire.

Orff started studying the piano at the age of five, and he also took organ and cello lessons. However, he was more interested in composing original music than in studying to be a performer. Orff wrote and staged puppet shows for his family, composing music for piano, violin, zither, and glockenspiel to accompany them. He had a short story published in a children's magazine in 1905 and started to write a book about nature. In his spare time he enjoyed collecting insects.

By the time he was a teenager, Orff was writing songs, although he had not studied harmony or composition; his mother helped him set down his first works in musical notation. Orff wrote his own texts and he learned the art of composing, without a teacher, by studying classical masterworks on his own.
