The 1980 New York City transit strike in New York City (often referred to as the Subway strike) was the first work stoppage at the New York City Transit Authority (a subsidiary of the New York MTA) since 1966.
 34,000 members of Transport Workers Union Local 100 walked off their jobs on April 1, 1980, in a strike with the goal of increasing the wage for contracted workers.
 All subway and bus lines in The Five Boroughs were brought to a complete standstill for ten days, during which the city lost an approximated $2 million a day in taxes and another $1 million a day in overtime expenses for city employees.
 Companies in the private sector lost approximately $100 million per day, and job absenteeism was estimated to be between 15 and 20 percent.
 The strike was resolved on April 11, with the TWU winning a 9% raise in the first year and 8% in the second year, along with a cost-of-living adjustment.
Chicago is an American rock band formed in 1967 in Chicago, Illinois.
 The self-described "rock and roll band with horns" began as a politically charged, sometimes experimental, rock band and later moved to a predominantly softer sound, generating several hit ballads.
 The group had a steady stream of hits throughout the 1970s and 1980s.
 Since at least 2008, "Billboard" has shown Chicago to be the "greatest of all time" American band in singles chart success, and since 2015, the "greatest of all time" American band in album chart success as well.
 Chicago is one of the longest-running and most successful rock groups, and one of the world's best-selling groups of all time, having sold more than 100 million records.
Katherine Oliver is an American media and entertainment executive based in New York City.
 Oliver is currently a Principal at Bloomberg Associates, a philanthropic consultancy firm founded by Michael Bloomberg to provide advice and long-term solutions to cities worldwide.
 On August 1, 2002, she was appointed by New York City Mayor Michael Bloomberg as the Commissioner of The New York City Mayor's Office of Film, Theatre and Broadcasting, which facilitates all aspects of film, television and commercial production in New York City, coordinating on-location filming, liaising with the community and promoting the City as an entertainment capital.
 Oliver was the main liaison between the Mayor's Office and Hollywood and aimed "to make filmmakers and production companies happy to return to New York."
 In 2013, Oliver and Mayor Bloomberg were featured on the cover of Variety and were credited for their role in "revitalizing the city's entertainment sector."
 An economic impact study released by the Boston Consulting Group in 2012 found that New York City's entertainment industry during Oliver's tenure as film commissioner had grown to account for a $7.1 billion annual direct spend in New York City, an increase of $2 billion since 2002, and that the local industry created 30,000 jobs in New York City since 2004, growing to employ 130,000 people.
 AM New York noted that: "New York's film and TV industry is stronger than it has ever been, pumping $7.1 billion into the local economy in 2011 and bringing in some $60 billion over the last decade."
 After Bloomberg announced that former president and co-founder of NYC Media Group Arick Wierson was returning to the private sector, Bloomberg named Oliver as the incoming president of NYC Media and general manager of NYCTV.
 In July 2010, Oliver became the commissioner of the Mayor's Office of Media and Entertainment, the city agency that includes the Mayor's Office of Film, Theatre and Broadcasting, NYC Media, and NYC Digital.

New York City has one of the largest and most prominent LGBT populations in the world.
 Brian Silverman, the author of "Frommer's New York City from $90 a Day", wrote the city has "one of the world's largest, loudest, and most powerful" LGBT communities" and "Gay and lesbian culture is as much a part of New York's basic identity as yellow cabs, high-rises, and Broadway theater."
 LGBT Americans in New York City constitute by significant margins the largest self-identifying lesbian, gay, bisexual and transgender communities in the United States, and the 1969 Stonewall Riots in Greenwich Village are widely considered to be the genesis of the modern gay rights movement.
 As of 2005, New York City was home to an estimated 272,493 self-identifying gay and bisexual individuals.
 The New York City metropolitan area had an estimated 568,903 self-identifying GLB residents.
 Meanwhile, New York City is also home to the largest transgender population in the United States, estimated at 25,000 in 2016.
"Another Rainy Day in New York City" is a song written by Robert Lamm for the group Chicago and recorded for their album "Chicago X" (1976).
 The first single released from that album, it reached #32 on the U.S. "Billboard" Hot 100 and it was a #2 hit on the Hot Adult Contemporary Tracks chart.
 The single, when released, was almost immediately ignored by radio in favor of the album cut "If You Leave Me Now".
 Due to this, Columbia Records ceased promotion of this single (accounting for its rather low chart placing) and rush-released "If You Leave Me Now" seven weeks after the release of "Another Rainy Day in New York City".
Judy Nylon is a widely influential multidisciplinary American artist who moved to London in 1970.
 She was half of the punk rock music group Snatch, which also featured fellow American expat Patti Palladin.
 Rock music aficionados living in New York City and London during the era spanning glam, punk and no wave are likely to appreciate her influence, the bulk of which has not been preserved in print nor on vinyl or CD.
 NME's Paul Tickell proclaimed her LP "Pal Judy" (1982), coproduced by Nylon and Adrian Sherwood, "a classic rainy day bit of sound and song to drift away to."
