Background: Carousel is the second musical by the team of Richard Rodgers (music) and Oscar Hammerstein II (book and lyrics). The 1945 work was adapted from Ferenc Molnar's 1909 play Liliom, transplanting its Budapest setting to the Maine coastline. The story revolves around carousel barker Billy Bigelow, whose romance with millworker Julie Jordan comes at the price of both their jobs. He participates in a robbery to provide for Julie and their unborn child; after it goes tragically wrong, he is given a chance to make things right.
Context: The cast album of the 1945 Broadway production was issued on 78s, and the score was significantly cut--as was the 1950 London cast recording. Theatre historian John Kenrick notes of the 1945 recording that a number of songs had to be abridged to fit the 78 format, but that there is a small part of "Soliloquy" found on no other recording, as Rodgers cut it from the score immediately after the studio recording was made.  A number of songs were cut for the 1956 film, but two of the deleted numbers had been recorded and were ultimately retained on the soundtrack album. The expanded CD version of the soundtrack, issued in 2001, contains all of the singing recorded for the film, including the cut portions, and nearly all of the dance music. The recording of the 1965 Lincoln Center revival featured Raitt reprising the role of Billy. Studio recordings of Carousel's songs were released in 1956 (with Robert Merrill as Billy, Patrice Munsel as Julie, and Florence Henderson as Carrie), 1962 and 1987. The 1987 version featured a mix of opera and musical stars, including Samuel Ramey, Barbara Cook and Sarah Brightman. Kenrick recommends the 1962 studio recording for its outstanding cast, including Alfred Drake, Roberta Peters, Claramae Turner, Lee Venora, and Norman Treigle.  Both the London (1993) and New York (1994) cast albums of the Hytner production contain portions of dialogue that, according to Hischak, speak to the power of Michael Hayden's portrayal of Billy. Kenrick judges the 1994 recording the best all-around performance of Carousel on disc, despite uneven singing by Hayden, due to Sally Murphy's Julie and the strong supporting cast (calling Audra McDonald the best Carrie he has heard). The Stratford Festival issued a recording in 2015.
Question: Who were main characters?
Answer: featured Raitt reprising the role of Billy.

Problem: Background: Abhay Charanaravinda Bhaktivedanta Swami Prabhupada (Abhoy Charonarobindo Bhoktibedanto Shwamy Probhupad; 1 September 1896 - 14 November 1977) was a Gaudiya Vaishnavism spiritual teacher (guru) and the founder preceptor (Acharya) of the International Society for Krishna Consciousness (ISKCON), commonly known as the "Hare Krishna Movement". Adherents of the ISKCON movement view Prabhupada as a divine avatar and messenger of Krishna. Born Abhay Charan De in Calcutta, he was educated at the Scottish Church College in Calcutta. Before adopting the life of a pious renunciant (vanaprastha) in 1950, he was married with children and owned a small pharmaceutical business.
Context: In 1922, when he first met his spiritual master, Bhaktisiddhanta Sarasvati Thakura, he was requested to spread the message of Chaitanya Mahaprabhu in the English language. In 1933 he became a formally initiated disciple of Bhaktisiddhanta. In 1944, (from his front room at Sita Kanta Banerjee, Calcutta), he started the publication called Back to Godhead, for which he acted as writer, designer, publisher, editor, copy editor and distributor. He personally designed the logo, an effulgent figure of Chaitanya Mahaprabhu in the upper left corner, with the motto: "Godhead is Light, Nescience is darkness" greeting the readers. In his first magazine he wrote:  Under the circumstances since 1936 up to now, I was simply speculating whether I shall venture this difficult task and that without any means and capacity; but as none have discouraged me, I have now taken courage to take up the work.  In 1947, the Gaudiya Vaishnava Society recognised his scholarship with the title Bhaktivedanta, (bhakti-vedanta) meaning "one who has realised that devotional service to the Supreme Lord is the end of all knowledge" (with the words Bhakti, indicating devotion and Vedanta indicating conclusive knowledge).  His later well known name, Prabhupada, is a Sanskrit title, literally meaning "he who has taken the shelter of the lotus feet of the Lord" where prabhu denotes "Lord", and pada means "taking shelter." Also, "at whose feet masters sit". This name was used as a respectful form of address by his disciples from late 1967 early 1968 onwards. Previous to this, as with his early disciples, followers used to call him "Swamiji".  From 1950 onwards, he lived at the medieval Radha-Damodar mandir in the holy town of Vrindavan, where he began his commentary and translation work of the Sanskrit work Bhagavata Purana. Of all notable Vrindavana's temples, the Radha-Damodara mandir had at the time the largest collection of various copies of the original writings of the Six Gosvamis and their followers - more than two thousand separate manuscripts, many of them three hundred, some even four hundred years old. His guru, Bhaktisiddhanta Sarasvati Thakura, had always encouraged him to print books, and beholding his spiritual master, Abhay felt the words deeply enter his own life - "If you ever get money, print books."  referring to the need of literary presentation of the Vaishnava culture.
