Context paragraphs:
Composers and Authors Society of Hong Kong: The Composers and Authors Society of Hong Kong Ltd.(CASH)  is a copyright society in Hong Kong established in 1977 which aims to administer and enforce collectively the rights of composers and authors of musical works subsisting under the copyright law of Hong Kong SAR.  Its motto is "your music partner" which demonstrates the relationship of CASH with its members, music users and public.  The word "Author" here stands for "Lyricist" instead of the common understanding of an author.  CASH has established the CASH Music Fund to promote a higher standard of local music composition and to encourage and develop songwriting talent by sponsoring a wide range of musical activities in Hong Kong.

Music of Luxembourg: The Music of Luxembourg is an important component of the country's cultural life.  The prestigious new Philharmonie concert hall provides an excellent venue for orchestral concerts while opera is frequently presented in the theatres.  Rock, pop and jazz are also popular with a number of successful performers.  The wide general interest in music and musical activities in Luxembourg can be seen from the membership of the Union Grand-Duc Adolphe, the national music federation for choral societies, brass bands, music schools, theatrical societies, folklore associations and instrumental groups.  Some 340 music groups and associations with over 17,000 individual members are currently represented by the organization.

All Things Must Pass: All Things Must Pass is a triple album by English musician George Harrison.  Recorded and released in 1970, the album was Harrison's first solo work since the break-up of the Beatles in April that year, and his third solo album overall.  It includes the hit singles "My Sweet Lord" and "What Is Life", as well as songs such as "Isn't It a Pity" and the title track that had been turned down for inclusion on releases by the Beatles.  The album reflects the influence of Harrison's musical activities with artists such as Bob Dylan, the Band, Delaney & Bonnie and Billy Preston during 1968–70, and his growth as an artist beyond his supporting role to former bandmates John Lennon and Paul McCartney.  "All Things Must Pass" introduced Harrison's signature sound, the slide guitar, and the spiritual themes that would be present throughout his subsequent solo work.  The original vinyl release consisted of two LPs of songs and a third disc of informal jams, titled "Apple Jam".  Several commentators interpret Barry Feinstein's album cover photo, showing Harrison surrounded by four garden gnomes, as a statement on his independence from the Beatles.

Waiting for Goddard: Waiting for Goddard is the title of the only album released by Steve Goddard.  Backed by some of the top musicians in the Christian music business of the era, Goddard's strong melodies and provocative lyrics were a big hit.  Nevertheless, his comments about the attitude displayed by members of the Church of England were controversial.  Goddard chose to limit his musical activities and concentrate on other activities.  He served for several years as editor of the evangelical youth magazine "Buzz" before beginning a new career as a public relations consultant.  In this last capacity his assignments have included promoting the Christian Resources Exhibition and the Library and Information Show.

Johann Karl von Ordonez: Johann Karl Rochus Ordoniz, also known as Karl von Ordoñez (April 19, 1734–September 6?  1786) was one of a number of composers working in Vienna during the second half of the Eighteenth century.  Ordonez was not a full-time professional musician.  Most of his working life was spent in the employment of the Lower Austrian Regional Court and his musical activities were pursued in his spare time.  Ordoñez's choice of career was probably dictated by his social rank.  As a member of the nobility, albeit of the lowest rank, he would have been aware that a professional musical career would not have befitted a man of his social standing.

Polovtsian Dances: The Polovtsian Dances, or Polovetsian Dances (Russian: Половецкие пляски, "Polovetskie plyaski" from the Russian "Polovtsy"—the name given to the Kipchaks and Cumans by the Rus' people) form an exotic scene at the end of Act II of Alexander Borodin's opera "Prince Igor".

The Daily News (San Francisco): The Daily News, later titled The San Francisco News, was a newspaper published in San Francisco, California.  It was founded in 1903 by E. W. Scripps as a four-page penny paper.  In its early years, it was the smallest of the several newspapers in San Francisco.  It advertised itself as the "friend of the working man."  It was only distributed in working class districts: Mission District, Skid Row, South of the Slot.  It specialized in short, easy-to-read stories one to two paragraphs long.  After the 1906 earthquake, it operated out of a former 720 sqft "relief house".  In 1919 it had a circulation of about 18,000.  It changed its name to "The San Francisco News" in 1927, and in August 1959 merged with Hearst's "The Call Bulletin" to form the "San Francisco News-Call Bulletin".

Cór Cois Abhann: Cór Cois Abhann (] , meaning "Riverside Choir") is an independent mixed voice choir based in Cork City Ireland.  Founded in 1990, the choir takes its name from the river that flows through the centre of the city.  The choir is currently directed by Ian Sexton and has performed large scale works including Verdi's "Messa da Requiem, Borodin's "Polovtsian Dances" and Duruflé's "Requiem (Opus 9)".

Gargoyle (band): Gargoyle is a thrash metal band in Japan.  The band was formed in July 1987, led by vocalist KIBA.  After some changes in members, they started musical activities in earnest in November 1988.  In April 1993, they signed for the major label Nippon Columbia, and released three studio albums (天論, 月の棘, natural)　and two compilation albums (異人伝, borderless).  From 1996, they went back to indie.  Now in 2017, they are still continuing their music activities energetically.

Gaudeamus Foundation: The Gaudeamus Foundation and Contemporary Music Center organizes and promotes contemporary musical activities and concerts in the Netherlands and abroad.  It focuses on supporting the career development of young composers and musicians, particularly Dutch, through its library facilities, contacts with international organizations, and its own activities.  Gaudeamus was founded at Bilthoven, the Netherlands, in 1945 by Walter A. F. Maas, a Jewish immigrant from Mainz.  It was originally headquartered in the Huize Gaudeamus, a villa built in the shape of a grand piano by the composer Julius Röntgen, also an immigrant from Germany but two generations older.  Although in 2008 the Gaudeamus Foundation was incorporated into the Muziek Centrum Nederland, as from 2011 it continues to operate independently.
