Answer the question at the end by quoting:

Jean-Philippe Rameau (French: [Zafilip Ramo]; (1683-09-25)25 September 1683 - (1764-09-12)12 September 1764) was one of the most important French composers and music theorists of the 18th century. He replaced Jean-Baptiste Lully as the dominant composer of French opera and is also considered the leading French composer for the harpsichord of his time, alongside Francois Couperin. Little is known about Rameau's early years, and it was not until the 1720s that he won fame as a major theorist of music with his Treatise on Harmony (1722) and also in the following years as a composer of masterpieces for the harpsichord, which circulated throughout Europe.
Unlike Lully, who collaborated with Philippe Quinault on almost all his operas, Rameau rarely worked with the same librettist twice. He was highly demanding and bad-tempered, unable to maintain longstanding partnerships with his librettists, with the exception of Louis de Cahusac, who collaborated with him on several operas, including Les fetes de l'Hymen et de l'Amour (1747), Zais (1748), Nais (1749), Zoroastre (1749; revised 1756), La naissance d'Osiris (1754), and Anacreon (the first of Rameau's operas by that name, 1754). He is also credited with writing the libretto of Rameau's final work, Les Boreades (c. 1763).  Many Rameau specialists have regretted that the collaboration with Houdar de la Motte never took place, and that the Samson project with Voltaire came to nothing because the librettists Rameau did work with were second-rate. He made his acquaintance of most of them at La Poupliniere's salon, at the Societe du Caveau, or at the house of the Comte de Livry, all meeting places for leading cultural figures of the day.  Not one of his librettists managed to produce a libretto on the same artistic level as Rameau's music: the plots were often overly complex or unconvincing. But this was standard for the genre, and is probably part of its charm. The versification, too, was mediocre, and Rameau often had to have the libretto modified and rewrite the music after the premiere because of the ensuing criticism. This is why we have two versions of Castor et Pollux (1737 and 1754) and three of Dardanus (1739, 1744, and 1760).

Was Louis de Cahusac his only librettist?

Rameau rarely worked with the same librettist twice.

Some context: Antoine Dominique "Fats" Domino Jr. (February 26, 1928 - October 24, 2017) was an American pianist and singer-songwriter. One of the pioneers of rock and roll music, Domino sold more than 65 million records. Between 1955 and 1960, he had eleven Top 10 hits. His humility and shyness may be one reason his contribution to the genre has been overlooked.
As Hurricane Katrina approached New Orleans in August 2005, Domino chose to stay at home with his family, partly because his wife, Rosemary, was in poor health. His house was in an area that was heavily flooded.  Domino was rumored to have died, and his home was vandalized when someone spray-painted the message "RIP Fats. You will be missed". On September 1, the talent agent Al Embry announced that he had not heard from Domino since before the hurricane struck. Later that day, CNN reported that Domino had been rescued by a Coast Guard helicopter. Until then, even family members had not heard from him since before the storm. Embry confirmed that Domino and his family had been rescued. The family was then taken to a shelter in Baton Rouge, after which they were picked up by JaMarcus Russell, the starting quarterback of the Louisiana State University football team, and the boyfriend of Domino's granddaughter. He let the family stay in his apartment. The Washington Post reported that on September 2, they had left Russell's apartment after sleeping three nights on the couch. "We've lost everything," Domino said, according to the Post.  By January 2006, work to gut and repair Domino's home and office had begun (see Reconstruction of New Orleans). In the meantime, the Domino family resided in Harvey, Louisiana.  President George W. Bush made a personal visit and replaced the National Medal of Arts that President Bill Clinton had previously awarded Domino. The gold records were replaced by the RIAA and Capitol Records, which owned the Imperial Records catalogue.
Did this affect his songwriting?

IN: Sarah Louise Palin ( ( listen); nee Heath; born February 11, 1964) is an American politician, commentator, and author who served as the ninth Governor of Alaska from 2006 until her resignation in 2009. As the Republican Party nominee for Vice President of the United States in the 2008 election alongside presidential nominee, Arizona Senator John McCain, she was the first Alaskan on the national ticket of a major political party and the first Republican woman selected as a vice presidential candidate. Her book Going Rogue has sold more than two million copies. She was elected to the Wasilla city council in 1992 and became mayor of Wasilla in 1996.

Palin had a contretemps with the Mat-Su Valley Frontiersman, a local newspaper, and reportedly became involved in personnel challenges and "a thwarted attempt to pack the City Council" during her first year in office. Using income generated by a 2% sales tax that had been approved by Wasilla voters in October 1992, Palin cut property taxes by 75% and eliminated personal property and business inventory taxes. Using municipal bonds, she made improvements to the roads and sewers and increased funding to the police department. She oversaw creation of new bike paths and procured funding for storm-water treatment to protect freshwater resources. At the same time, she shrank the local museum's budget and deterred talk of a new library and city hall.  Soon after taking office in October 1996, Palin eliminated the position of museum director and asked for updated resumes and resignation letters from "city department heads who had been loyal to Stein", including the police chief, public works director, finance director, and librarian. Palin stated this request was to find out their intentions and whether they supported her. She temporarily required department heads to get her approval before talking to reporters, saying they first needed to become acquainted with her administration's policies. She created the position of city administrator and reduced her own $68,000 salary by 10%, although by mid 1998 this was reversed by the city council.  In October 1996, Palin asked library director Mary Ellen Emmons if she would object to the removal of a book from the library if people were picketing to have the book removed. Emmons responded that she would, and others as well. Palin stated that she had not been proposing censorship but had been discussing many issues with her staff that were "both rhetorical and realistic in nature." No attempt was made to remove books from the library during Palin's tenure as mayor.  Palin said she fired Police Chief Irl Stambaugh because he did not fully support her efforts to govern the city. Stambaugh filed a lawsuit alleging wrongful termination and violation of his free speech rights. The judge dismissed Stambaugh's lawsuit, holding that the police chief served at the discretion of the mayor and could be terminated for nearly any reason, even a political one, and ordered Stambaugh to pay Palin's legal fees.

Who did she appoint in his stead?
