10 Downing Street, colloquially known in the United Kingdom as "Number 10", is the headquarters of Her Majesty's Government and the official residence and office of the First Lord of the Treasury, an office now invariably held by the Prime Minister.

Situated on Downing Street in the City of Westminster, London, Number 10 is one of the most famous addresses in the United Kingdom and the world. Almost three hundred years old, the building contains about one hundred rooms. There is a private residence on the third floor and a kitchen in the basement. The other floors contain offices and numerous conference, reception, sitting and dining rooms where the Prime Minister works, and where government ministers, national leaders and foreign dignitaries are met and entertained. There is an interior courtyard and, in the back, a terrace overlooking a garden of 0.5 acres (2,000 m²). Adjacent to St. James's Park, Number 10 is near the Houses of Parliament, and Buckingham Palace, the official London residence of the British Monarch.

Dmitri Dmitriyevich Shostakovich Russian pronunciation: [ˈdmʲitrʲɪj ˈdmʲitrʲɪɪvʲɪt͡ɕ ʂəstɐˈkovʲɪt͡ɕ] (Russian: Дмитрий Дмитриевич Шостакович; 25 September 1906 – 9 August 1975) was a Soviet Russian composer and pianist and was one of the most celebrated composers of the 20th century.

Shostakovich achieved fame in the Soviet Union under the patronage of Leon Trotsky's chief of staff Mikhail Tukhachevsky, but later had a complex and difficult relationship with the government. Nevertheless, he received accolades and state awards and served in the Supreme Soviet of the RSFSR (1947–1962) and the USSR (from 1962 until death).

After a period influenced by Sergei Prokofiev and Igor Stravinsky, Shostakovich developed a hybrid style, as exemplified by Lady Macbeth of the Mtsensk District (1934). This single work juxtaposed a wide variety of trends, including the neo-classical style (showing the influence of Stravinsky) and post-Romanticism (after Gustav Mahler). Sharp contrasts and elements of the grotesque characterize much of his music.

David Starobin (born September 27, 1951 in New York City) is an American classical guitarist, record producer, and film director. He is married to Rebecca Askew Starobin (married 1975), and is the father of Robert Joseph Starobin III (b. 1979), and Allegra Rose Starobin (b. 1987).

Starobin started playing the guitar at the age of seven, studying first with Manuel Gayol, then Albert Valdes Blain and at the Peabody Conservatory of Johns Hopkins University (Baltimore) with Aaron Shearer. While at Peabody he became Shearer's assistant, directing Peabody's chamber music program for guitarists (1971–73). During this period Starobin worked closely with pianist Leon Fleisher, becoming a member of Fleisher's Theater Chamber Players of The John F. Kennedy Center (Washington D.C.).

David Starobin has toured in the USA as a recitalist, chamber player and orchestral soloist performing at festivals including Marlboro, Aspen, Santa Fe Chamber, and Tanglewood, and with orchestras and ensembles including the New York Philharmonic, Houston Symphony, San Francisco Symphony, National Symphony Orchestra, and the Emerson and Guarneri String Quartets as well as the Chamber Music Society of Lincoln Center. Since 1978 he has made annual solo tours in Europe, performing at festivals and making radio and television broadcasts. Starobin is a member of the new music ensemble Speculum Musicae, with whom he has performed and recorded as guitarist and conductor. He also recorded and toured since 1969 with the baritone, Patrick Mason. With the percussionist Daniel Druckman, Mason and Starobin have performed and recorded as the trio, "Crazy Jane".

Ian Levine (born 22 June 1953, in Blackpool, Lancashire) is an English songwriter, producer, and DJ. He is also a well-known fan of the long-running television show Doctor Who.

Levine attended Arnold (House) School in Blackpool from 1963 to 1970. In 1996 Levine traced over 660 members of his own family on his mother's side and organised the enormous Cooklin family reunion, on 21 July in London. This has been called the biggest family reunion of all time^{[citation needed]}, and was covered on the BBC Evening News, and, extensively, in The Jewish Chronicle.

Between 1997 and 1999 Ian Levine produced and directed the documentary film The Strange World of Northern Soul, an anthology of the underground music cult. This was a video box set, containing over 12 hours of footage with booklet and CD, and incorporating 131 performances by the legendary American soul acts who had, in most cases, never been filmed before. The event premiered at the King George's Hall in Blackburn to an audience of 1300 in July 1999. The Strange World of Northern Soul was released on DVD as a six-disc box set, replete with extras, in 2003.
