Question: Who sang the theme song for a British comedy-drama television programme about seven British migrant construction workers?

Context paragraphs:
Nepalis in Qatar: Nepalis in Qatar are migrants from Nepal to Qatar, mostly migrant workers and permanent residents, as well as their locally born descendants.  As of 2011-2014 report by International Organization for Migration, 176,748 Nepali Citizens lived in Qatar as migrant workers.  While there are Nepalese working in the business and administrative sectors of Qatar, most workers from Nepal fall under the umbrella of unskilled labor, and hold jobs in sectors such as construction and landscaping.  Many workers from Nepal are hired to work on the construction of stadiums and railways that are being designed for the 2022 FIFA World Cup to be held in Qatar.  According to "Time Magazine", due to the terrible working conditions in Qatar, a Nepali World Cup worker dies every other day.

Murphy's Mob: Murphy's Mob is a British children's television series, created and written by Brian Finch which was produced and directed by David Foster for Central Television, and screened in the UK on ITV for four series between 1982 and 1985.  The theme tune was sung by Gary Holton, of "Auf Wiedersehen, Pet" fame.

Human trafficking in the Maldives: The Maldives is primarily a destination country for migrant workers from Bangladesh, and, to a lesser extent, India, some of whom are subjected to trafficking in persons, specifically forced labor.  Some women are also subjected to forced prostitution.  An unknown number of the 110,000 foreign workers currently working in the Maldives – primarily in the construction and service sectors – face fraudulent recruitment practices, confiscation of identity and travel documents, withholding or non-payment of wages, or debt bondage.  Thirty thousand of these workers do not have legal status in the country, though both legal and illegal workers were vulnerable to conditions of forced labor.  Diplomatic sources estimate that half of the 35,000 Bangladeshis in the Maldives went there illegally and that most of these workers are probably victims of trafficking.  Migrant workers pay $1,000 to $4,000 in recruitment fees in order to migrate to the Maldives; such high recruitment costs increase workers’ vulnerability to forced labor, as concluded in a recent ILO report.

Construction industry of Japan: In Japan, the mainstay of infrastructure development is the construction industry, which employed 9.4 percent of the labor force in 1990 and contributed some 8.5 percent of GDP.  After the two oil crises (1973 and 1979) in the 1970s, construction investment turned sluggish, and the share of construction investment in GNP decreased gradually.  In 1987, however, business expanded through investor confidence, continued increase in corporate earnings, improvement of personal income, and rapid rise in land prices.  The share of construction investment in GNP rose sharply, especially for more sophisticated and higher value-added private housing and private non-housing structures (see table 19, Appendix).  After employment peaking at 9.9% in 2003, the construction industry in Japan has entered a long, steady decline with workers share dropping to 7.0% by 2017.  This decline is attributed to gradually slumping demand for the new houses.  Japanese construction worker productivity have surpassed US productivity in 2006, but as in 2017, productivity of 0.24 houses/worker*year is still below peak value of 0.32 houses/worker*year in 1992.  This downward trend (although less pronounced than in the US) is mostly attributed to the increasing median age of the construction workers.  The productivity on concrete-making industry remains on the level along with the most productive countries, with the 1.29 man-hours per cubic meter reported in 2011 (with the leading US having 1.00 man-hours per cubic meter).

Rajasthan Nirman Mazdoor Sangathan: Rajasthan Nirman Mazdoor Sangathan (Rajasthan Construction Workers Organization) is a trade union of construction workers in Rajasthan, India.  RNMS is affiliated to All India Central Council of Trade Unions.  The President of RNMS is Shrilata Swaminathan.

Bloemfontein Conference: The Bloemfontein Conference was a meeting that took place in Bloemfontein, capital of the Orange Free State from May 31 until June 5, 1899.  The main issue dealt with the status of British migrant workers called "Uitlanders", who mined the gold fields in Transvaal.

Human trafficking in Indonesia: Indonesia is a source, transit, and destination country for women, children, and men trafficked for the purposes of commercial sexual exploitation and forced labor.  The greatest threat of trafficking facing Indonesian men and women is that posed by conditions of forced labor and debt bondage in more developed Asian countries and the Middle East.  The government stopped permitting Indonesian women to travel to Japan and South Korea as “cultural performers,” to curtail a practice that led to victims being trafficked for commercial sexual exploitation.  However, in 2007 traffickers increasingly used false documents, including passports, to obtain tourist visas for women and girls who are subsequently forced into prostitution in Japan, through the unlawful exploitation of recruitment debts as high as $20,000 each.  Trafficking of young girls to Taiwan as brides, mainly from West Kalimantan, persisted.  Traffickers use false marriage licenses and other false documentation in order to obtain visas and subsequently force the women and girls into prostitution.  Women from the People’s Republic of China, Thailand, and Eastern Europe are trafficked to Indonesia for commercial sexual exploitation, although the numbers are small compared with the number of Indonesians trafficked for this purpose.  A significant number of Indonesian men and women who migrate overseas each year to work in the construction, agriculture, manufacturing, and domestic service sectors are subjected to conditions of forced labor or debt bondage in Malaysia, Saudi Arabia, Iraq, Singapore, Taiwan, Hong Kong, United Arab Emirates, Jordan, Kuwait, Qatar, Syria, France, Belgium, Germany, and the Netherlands.  Malaysia and Saudi Arabia are the top destinations for legal and illegal Indonesian migrant workers who are trafficked for domestic servitude, commercial sexual exploitation, and forced labor.  Some labor recruitment companies, known as PJTKIs, operated similarly to trafficking rings, luring both male and female workers into debt bondage, involuntary servitude, and other trafficking situations.  Some workers, often women intending to migrate, entered trafficking and trafficking-like situations during their attempt to find work abroad through licensed and unlicensed PJTKIs.  These labor recruiters charged workers high commission fees—up to $3,000—which are not regulated under Indonesian law and often require workers to incur debt to pay, leaving them vulnerable in some instances to situations of debt bondage.  PJTKIs also reportedly withheld the documents of some workers, and confined them in holding centers, sometimes for periods of many months.  Some PJTKIs also used threats of violence to maintain control over prospective migrant workers.  Recruitment agencies routinely falsified birth dates, including for children, in order to apply for passports and migrant worker documents.  Internal trafficking is a significant problem in Indonesia with women and children exploited in domestic servitude, commercial sexual exploitation, rural agriculture, mining, fishing, and cottage industries.  Women and girls are trafficked into commercial sexual exploitation in Malaysia, Singapore, and throughout Indonesia.  Indonesians are recruited with offers of jobs in restaurants, factories, or as domestics and then forced into the sex trade.  Young women and girls are trafficked throughout Indonesia and via the Riau Islands, Kalimantan, and Sulawesi to Malaysia and Singapore.  Malaysians and Singaporeans constitute the largest number of sex tourists, and the Riau Islands and surrounding areas operate a “prostitution economy,” according to local officials.  Sex tourism is rampant in most urban areas and tourist destinations.  A 2006 bilateral MOU between the Indonesian and Malaysian governments, governing the employment of an estimated one million Indonesian domestic workers in Malaysia, failed to provide adequate protection to Indonesian migrant workers and explicitly endorsed a practice that is widely seen as a potential facilitator of forced labor—the right of Malaysian employers to hold the passports of Indonesian workers.  This agreement has not been amended to offer protections from forced labor conditions.

Auf Wiedersehen, Pet: Auf Wiedersehen, Pet (] , "Goodbye, Pet") is a British comedy-drama television programme about seven British migrant construction workers.  In the first series, the men live and work on a building site in Düsseldorf.

Aa (architect): Aa, possibly AaAa (ˁȝˁȝ), was an ancient Egyptian architect and construction supervisor.  His title was "Overseer of construction workers" or "Great Overseer of construction workers".  He lived in the time of the Middle Kingdom of Egypt (between 2080 BCE and 1640 BCE).

Culture of the Isle of Man: The culture of the Isle of Man is influenced by its Celtic and, to a lesser extent, its Norse origins, though its close proximity to the United Kingdom, popularity as a UK tourist destination, and recent mass immigration by British migrant workers has meant that British influence has been dominant since the Revestment period.  Recent revival campaigns have attempted to preserve the surviving vestiges of Manx culture after a long period of Anglicisation, and significant interest in the Manx language, history and musical tradition has been the result.
