Question: Who is the composer of the performance named "The Beggar's" followed by the word sub-classifying sung-through?

full_context: Document 1: Sung-through: A sung-through (also through-sung) musical, musical film, or opera is one with no spoken dialogue, except perhaps for some occasional lines spoken in the course of a song but remaining part of the song's lyrics rather than constituting stand-alone dialogue.
Document 2: The Beggar's Opera: The Beggar's Opera is a ballad opera in three acts written in 1728 by John Gay with music arranged by Johann Christoph Pepusch. It is one of the watershed plays in Augustan drama and is the only example of the once thriving genre of satirical ballad opera to remain popular today. Ballad operas were satiric musical plays that used some of the conventions of opera, but without recitative. The lyrics of the airs in the piece are set to popular broadsheet ballads, opera arias, church hymns and folk tunes of the time.
Document 3: Strolling Actresses Dressing in a Barn: Strolling Actresses Dressing in a Barn is a painting from 1738 by British artist William Hogarth. It was reproduced as an engraving and issued with "Four Times of the Day" as a five print set in the same year. The painting depicts a company of actresses preparing for their final performance before the troupe is disbanded as a result of the Licensing Act 1737. Brought in as a result of John Gay's "Beggar's Opera" of 1728, which had linked Robert Walpole with the notorious criminal Jonathan Wild, the Licensing Act made it compulsory for new plays to be approved by the Lord Chamberlain, and, more importantly for the characters depicted, closed any non-patent theatres. The majority of the painting was completed before the Act was passed in 1737, but its passing into law was no surprise and it was the work of a moment for Hogarth to insert a reference to the Act itself into the picture.
Document 4: A cappella: A cappella [a kapˈpɛlla] (Italian for "in the manner of the chapel") music is specifically group or solo singing without instrumental accompaniment, or a piece intended to be performed in this way. It contrasts with cantata, which is accompanied singing. The term "a cappella" was originally intended to differentiate between Renaissance polyphony and Baroque concertato style. In the 19th century a renewed interest in Renaissance polyphony coupled with an ignorance of the fact that vocal parts were often doubled by instrumentalists led to the term coming to mean unaccompanied vocal music. The term is also used, albeit rarely, as a synonym for alla breve.
Document 5: Sanskrit: Satyagraha, an opera by Philip Glass, uses texts from the Bhagavad Gita, sung in Sanskrit. The closing credits of The Matrix Revolutions has a prayer from the Brihadaranyaka Upanishad. The song "Cyber-raga" from Madonna's album Music includes Sanskrit chants, and Shanti/Ashtangi from her 1998 album Ray of Light, which won a Grammy, is the ashtanga vinyasa yoga chant. The lyrics include the mantra Om shanti. Composer John Williams featured choirs singing in Sanskrit for Indiana Jones and the Temple of Doom and in Star Wars: Episode I – The Phantom Menace. The theme song of Battlestar Galactica 2004 is the Gayatri Mantra, taken from the Rigveda. The lyrics of "The Child In Us" by Enigma also contains Sanskrit verses.[better source needed].
Document 6: Lancashire: Lancashire has a long and highly productive tradition of music making. In the early modern era the county shared in the national tradition of balladry, including perhaps the finest border ballad, "The Ballad of Chevy Chase", thought to have been composed by the Lancashire-born minstrel Richard Sheale. The county was also a common location for folk songs, including "The Lancashire Miller", "Warrington Ale" and "The soldier's farewell to Manchester", while Liverpool, as a major seaport, was the subject of many sea shanties, including "The Leaving of Liverpool" and "Maggie May", beside several local Wassailing songs. In the Industrial Revolution changing social and economic patterns helped create new traditions and styles of folk song, often linked to migration and patterns of work. These included processional dances, often associated with rushbearing or the Wakes Week festivities, and types of step dance, most famously clog dancing.
Document 7: John Playford: John Playford (1623–1686/7) was a London bookseller, publisher, minor composer, and member of the Stationers' Company, who published books on music theory, instruction books for several instruments, and psalters with tunes for singing in churches. He is perhaps best known today for his publication of "The English Dancing Master" in 1651.
Document 8: Classical music: Vocal music in the Renaissance is noted for the flourishing of an increasingly elaborate polyphonic style. The principal liturgical forms which endured throughout the entire Renaissance period were masses and motets, with some other developments towards the end, especially as composers of sacred music began to adopt secular forms (such as the madrigal) for their own designs. Towards the end of the period, the early dramatic precursors of opera such as monody, the madrigal comedy, and the intermedio are seen.
Document 9: A cappella: In the Byzantine Rite of the Eastern Orthodox Church and the Eastern Catholic Churches, the music performed in the liturgies is exclusively sung without instrumental accompaniment. Bishop Kallistos Ware says, "The service is sung, even though there may be no choir... In the Orthodox Church today, as in the early Church, singing is unaccompanied and instrumental music is not found." This a cappella behavior arises from strict interpretation of Psalms 150, which states, Let every thing that hath breath praise the Lord. Praise ye the Lord. In keeping with this philosophy, early Russian musika which started appearing in the late 17th century, in what was known as khorovïye kontsertï (choral concertos) made a cappella adaptations of Venetian-styled pieces, such as the treatise, Grammatika musikiyskaya (1675), by Nikolai Diletsky. Divine Liturgies and Western Rite masses composed by famous composers such as Peter Tchaikovsky, Sergei Rachmaninoff, Alexander Arkhangelsky, and Mykola Leontovych are fine examples of this.
Document 10: The Court Beggar: The Court Beggar is a Caroline era stage play written by Richard Brome. It was first performed by the acting company known as Beeston's Boys at the Cockpit Theatre. It has sometimes been identified as the seditious play, performed at the Cockpit in May 1640, which the Master of the Revels moved to have suppressed. However, the play's most recent editor, Marion O'Connor, dates it to "no earlier than the end of November 1640, and perhaps in the first months of 1641".
Document 11: A Harlot's Progress (opera): A Harlot's Progress is an opera in six scenes by the British composer Iain Bell which is based on William Hogarth's series of etchings of the same name. The libretto is by British author Peter Ackroyd.
Document 12: Vocal jazz: Vocal jazz or jazz singing is an instrumental approach to the voice, where the singer can match the instruments in their stylistic approach to the lyrics, improvised or otherwise, or through scat singing; that is, the use of non-morphemic syllables to imitate the sound of instruments.
Document 13: A cappella: The Swingle Singers used nonsense words to sound like instruments, but have been known to produce non-verbal versions of musical instruments. Like the other groups, examples of their music can be found on YouTube. Beatboxing, more accurately known as vocal percussion, is a technique used in a cappella music popularized by the hip-hop community, where rap is often performed a cappella also. The advent of vocal percussion added new dimensions to the a cappella genre and has become very prevalent in modern arrangements. Petra Haden used a four-track recorder to produce an a cappella version of The Who Sell Out including the instruments and fake advertisements on her album Petra Haden Sings: The Who Sell Out in 2005. Haden has also released a cappella versions of Journey's "Don't Stop Believin'", The Beach Boys' "God Only Knows" and Michael Jackson's "Thriller". In 2009, Toyota commissioned Haden to perform three songs for television commercials for the third-generation Toyota Prius, including an a cappella version of The Bellamy Brothers' 1970s song "Let Your Love Flow".[citation needed]
Document 14: The Beggar's Opera: "The Beggar's Opera" premiered at the Lincoln's Inn Fields Theatre on 29 January 1728 and ran for 62 consecutive performances, the second longest run in theatre history up to that time (after 146 performances of Robert Cambert's "Pomone" in Paris in 1671). The work became Gay's greatest success and has been played ever since; it has been called "the most popular play of the eighteenth century." In 1920, "The Beggar's Opera" began a revival run of 1,463 performances at the Lyric Theatre in Hammersmith, London, which was one of the longest runs in history for any piece of musical theatre at that time.
Document 15: Over the Hills and Far Away (traditional song): ``Over the Hills and Far Away ''is a traditional British song, dating back to at least the late 17th century. One version was published in Thomas D'Urfey's Wit and Mirth, or Pills to Purge Melancholy; a very different one appeared in George Farquhar's 1706 play The Recruiting Officer. A version also appears in John Gay's The Beggar's Opera of 1728.
