full_context: Document 1: James Curtiss: James Curtiss (also Curtis) (March 29, 1806 – November 2, 1859) was an American politician who twice served as Mayor of Chicago, Illinois (1847–1848 and 1850–1851) for the Democratic Party.
Document 2: Adult contemporary music: After 1965, differences between the Hot 100 chart and the Easy Listening chart became more pronounced. Better reflecting what middle of the road stations were actually playing, the composition of the chart changed dramatically. As rock music continued to harden, there was much less crossover between the Hot 100 and Easy Listening chart than there had been in the early half of the 1960s. Roger Miller, Barbra Streisand and Bobby Vinton were among the chart's most popular performers.
Document 3: William Hale Thompson: William Hale Thompson (May 14, 1869 -- March 19, 1944) was an American politician, mayor of Chicago for three terms, from 1915 to 1923 and again from 1927 to 1931. Known as ``Big Bill ''Thompson, he is the last Republican to have served as mayor of Chicago to date. Historians rank Thompson among the most unethical mayors in American history, mainly for his open alliance with Al Capone. However, others recognize the effectiveness of his political methods and publicity - oriented campaigning, acknowledging him as a`` Political Chameleon'' and an effective political machine. TIME magazine said in 1931, ``chief credit for creating 20th Century Politics Chicago Style ''should go to William Thompson.
Document 4: The Muse (soundtrack): The Muse is a soundtrack released by singer Elton John in August 1999 for the original motion picture "The Muse". The album is a departure for Elton, as it is mainly the orchestrated score of the film, which he wrote in its entirety. The only vocal track is the title track, which was co-written with longtime lyricist Bernie Taupin.
Document 5: Adult contemporary music: Much of the music recorded by singer-songwriters such as Diana Ross, James Taylor, Carly Simon, Carole King and Janis Ian got as much, if not more, airplay on this format than on Top 40 stations. Easy Listening radio also began including songs by artists who had begun in other genres, such as rock and roll or R&B. In addition, several early disco songs, did well on the Adult Contemporary format.
Document 6: Bernie Taupin: Bernard John Taupin (born 22 May 1950) is an English lyricist, poet, and singer, best known for his long - term collaboration with Elton John, writing the lyrics for the majority of the star's songs.
Document 7: Adult contemporary music: The "soft" AC format has reinvented in the late 2000s/early 2010s as a result of its declining relevance, adopting a more upmarket, middle-of-the-road approach, with a selection of "oldies" (usually from the 1960s/70s onwards), primarily rock, jazz, R&B and pop music. Newer songs are more often (but not limited to) "easy listening" fare, this amount varying depending on the age of the station's target demographic.
Document 8: Adult contemporary music: The Hot 100 and Easy Listening charts became more similar again toward the end of the 1960s and into the early and mid-1970s, when the texture of much of the music played on Top 40 radio once more began to soften. The adult contemporary format began evolving into the sound that later defined it, with rock-oriented acts as Chicago, The Eagles, and Elton John becoming associated with the format.
Document 9: William M. Tweed: William Magear Tweed (April 3, 1823 -- April 12, 1878) -- often erroneously referred to as ``William Marcy Tweed ''(see below), and widely known as`` Boss'' Tweed -- was an American politician most notable for being the ``boss ''of Tammany Hall, the Democratic Party political machine that played a major role in the politics of 19th century New York City and State. At the height of his influence, Tweed was the third - largest landowner in New York City and a director of the Erie Railroad, the Tenth National Bank, and the New - York Printing Company, as well as proprietor of the Metropolitan Hotel.

Document 11: The Last Song (Elton John song): "The Last Song" is the second single from Elton John's 1992 album, "The One". It was composed by John, with lyrics provided by Bernie Taupin. "The Last Song" marked the first of John's American singles to benefit his AIDS foundation. Taupin faxed the lyrics to him in Paris, shortly after Queen lead singer Freddie Mercury died the previous year. "I was crying all the time as I wrote the music", John told "The Advocate", "and it was very hard for me to sing it". The song tells of an estranged father coming to terms with the sexuality of his gay son, who is dying of an AIDS-related illness. Originally titled "Song for 1992", it was renamed to avoid dating it.
Document 12: Adult contemporary music: Hard rock had been established as a mainstream genre by 1965. From the end of the 1960s, it became common to divide mainstream rock music into soft and hard rock, with both emerging as major radio formats in the US. Soft rock was often derived from folk rock, using acoustic instruments and putting more emphasis on melody and harmonies. Major artists included Barbra Streisand, Carole King, Cat Stevens, James Taylor and Bread.
