Question:
West Side Story is a musical with a book by Arthur Laurents, music by Leonard Bernstein, lyrics by Stephen Sondheim and conception and choreography by Jerome Robbins. It was inspired by William Shakespeare's play Romeo and Juliet. The story is set in the Upper West Side neighborhood in New York City in the mid 1950s, an ethnic, blue-collar neighborhood (in the early 1960s, much of the neighborhood was cleared in an urban renewal project for the Lincoln Center, which changed the neighborhood's character). The musical explores the rivalry between the Jets and the Sharks, two teenage street gangs of different ethnic backgrounds.
The original Australian production opened in October 1960 at the Princess Theatre in Melbourne, before touring to the Tivoli Theatre in Sydney in February 1961. Subsequent Australian national tours have been staged in 1983, 1994 and 2010. In 1961, a tour of Israel, Africa and the Near East was mounted. In February 1962, the West End (H. M. Tennent) production launched a five-month Scandinavian tour opening in Copenhagen, continuing to Oslo, Gothenburg, Stockholm and Helsinki. Robert Jeffrey took over from David Holliday as Tony and Jill Martin played Maria. In 1977, Amor Sin Barreras was produced in Mexico City by Alfonso Rosas Prigo, & Ruben Boido, Direction by Ruben Boido, presented at the Hidalgo Theater. Gualberto Castro played the part of Tony; Maria Medina was Maria, among other cast members was Macaria. From 1982-1984 a tour of South America, Israel and Europe was mounted with talent from New York. The Director/Choreographers for that production were Jay Norman and Lee Theodore, veterans of the original Broadway cast. The Japanese Takarazuka Revue has performed the show twice. It was produced by the Moon Troupe in 1998 and again in 1999 by the Star Troupe. A Hong Kong production was produced in 2000 with Cantonese lyrics, featuring Hong Kong rock star Paul Wong as Tony. It was staged at the outdoor plaza of Hong Kong Cultural Centre. Canada's Stratford Shakespeare Festival performed West Side Story in 1999, starring Tyley Ross as Tony and Ma-Anne Dionisio as Maria, and again in 2009, The Austrian Bregenz Festival presented West Side Story in a German translation by Marcel Prawy in 2003 and 2004, directed by the Francesca Zambello, followed by a German tour. A French language adaptation, translated by Philippe Gobeille, opened in Montreal, Quebec in March 2008. A Philippine version played in 2008 at the Meralco Theatre. It featured Christian Bautista as Tony, Karylle and Joanna Ampil as Maria. Also in 2008, an adaptation played in Portugal, directed by Filipe La Feria, with the name West Side Story - Amor Sem Barreiras, in the Politeama Theater, in Lisbon, with Ricardo Soler as Tony and Lucia Moniz and Anabela splitting the role of Anita. An international tour (2005-2010), directed and choreographed by Joey McKneely played in Tokyo, Paris, Austria, Switzerland, Germany, Singapore, Sao Paulo, France, Taiwan, China, Italy, Rotterdam and Madrid.

Question:
Cher (; born Cherilyn Sarkisian (Armenian: Sherilin Sargsyan); May 20, 1946) is an American singer and actress. Sometimes called the Goddess of Pop, she has been described as embodying female autonomy in a male-dominated industry. She is known for her distinctive contralto singing voice and for having worked in numerous areas of entertainment, as well as adopting a variety of styles and appearances during her six-decade-long career.
At age 16, Cher dropped out of school, left her mother's house, and moved to Los Angeles with a friend. She took acting classes and worked to support herself, dancing in small clubs along Hollywood's Sunset Strip and introducing herself to performers, managers, and agents. According to Berman, "[Cher] did not hesitate to approach anyone she thought could help her get a break, make a new contact, or get an audition." Cher met performer Sonny Bono in November 1962 when he was working for record producer Phil Spector. Cher's friend moved out, and Cher accepted Sonny's offer to be his housekeeper. Sonny introduced Cher to Spector, who used her as a backup singer on many recordings, including the Ronettes' "Be My Baby" and the Righteous Brothers' "You've Lost That Lovin' Feelin'". Spector produced her first single, the commercially unsuccessful "Ringo, I Love You", which Cher recorded under the name Bonnie Jo Mason. Cher and Sonny became close friends, eventual lovers, and performed their own unofficial wedding ceremony in a hotel room in Tijuana, Mexico, on October 27, 1964. Although Sonny had wanted to launch Cher as a solo artist, she encouraged him to perform with her because she suffered from stage fright, and he began joining her onstage, singing the harmonies. Cher disguised her nervousness by looking at Sonny; she later commented that she sang to the people through him. In late 1964, they emerged as a duo called Caesar & Cleo, releasing the poorly received singles "Do You Wanna Dance?", "Love Is Strange", and "Let the Good Times Roll". Cher signed with Liberty Records' Imperial imprint in the end of 1964, and Sonny became her producer. The single "Dream Baby", released under the name "Cherilyn", received airplay in Los Angeles. Encouraged by Imperial, Cher worked with Sonny on her second solo single on the label, a cover version of Bob Dylan's "All I Really Want to Do", which peaked at number 15 on the U.S. Billboard Hot 100 in 1965. Meanwhile, the Byrds had released their own version of the same song. When competition on the singles charts started between Cher and the Byrds, the group's record label began to promote the B-side of the Byrds' single. Roger McGuinn of the Byrds commented, "We loved the Cher version ... We didn't want to hassle. So we just turned our record over." Cher's debut album, All I Really Want to Do (1965), reached number 16 on the Billboard 200; it was later described by AllMusic's Tim Sendra as "one of the stronger folk-pop records of the era".
