Poulenc wrote the piece in response to the death of his friend, artist Christian Bérard; he considered writing a Requiem for Bérard, but, after returning to the shrine of the Black Virgin of Rocamadour, he selected the medieval "Stabat Mater" text.  Poulenc's setting, scored for soprano solo, mixed chorus, and orchestra, premiered in 1951 at the Strasbourg Festival.  The "Stabat Mater" was well-received throughout Europe, and in the United States it won the New York Critics’ Circle Award for Best Choral Work of the year.

Mandeville-Anthony v. Walt Disney Co.: Mandeville-Anthony v.  The Walt Disney Company, 11-56441 (9th Cir.  2012), is a United States Court of Appeals for the Ninth Circuit case in which the Court evaluated whether defendants Pixar, The Walt Disney Company and Walt Disney Pictures infringed on Jake Mandeville-Anthony's copyrighted works.  Plaintiff Mandeville-Anthony's claim for copyright infringement was first dismissed by the United States District Court for the Central District of California, because the court found that the parties’ works were not substantially similar.  Mandeville-Anthony made copyright infringement claims with regards to his works "Cookie & Co." and "Cars/Auto-Excess/Cars Chaos", an animated television show and movie, that he believed Disney copied in order to make their own films, "Cars" and "Cars 2", both of which were very successful, and animation television show "Cars Toons: Mater's Tall Tales".  He also made breach of contract claims stating that he and Disney signed a contract barring Disney from using the ideas contained in his works.  The decision was affirmed by the Court of Appeals.

BTC-T Honda Integra Type R: In 2005, Team Dynamics took advantage of a loophole in the British Touring Car Championship regulations that allowed cars to enter, whether they were on sale in the United Kingdom or not.  They converted a pair of Honda Integra Type R Japanese imports into full blown BTC Touring spec racing cars, using the internals from the moderately successful Honda Civic Type R that had been competing in the BTCC since 2002.  The car was an instant hit, winning its debut race at Donington Park despite only having a limited amount of testing.  Matt Neal scored points in every single race to take his first BTCC title - the first for a privateer driver in the modern era.  He repeated the feat in 2006 and by that point, five cars had been built, all of them race winners in the hands of the Dynamics drivers, before being passed into the hands of various independent teams.  The cars remained in the championship until 2011, in the hands of Lea Wood, even finishing 7th at Oulton Park in that final season - an impressive result for a car that had been built 6 years previously.  Indeed, it was the last of the BTC-Touring spec cars to be used in the BTCC; and was only finally retired as cars built to these regulations could no longer compete in 2012.

Stock car (rail): In railroad terminology, a stock car, cattle car or cattle wagon (British English) is a type of rolling stock used for carrying livestock (not carcasses) to market.  A traditional stock car resembles a boxcar with louvered instead of solid car sides (and sometimes ends) for the purpose of providing ventilation; stock cars can be single-level for large animals such as cattle or horses, or they can have two or three levels for smaller animals such as sheep, pigs, and poultry.  Specialized types of stock cars have been built to haul live fish and shellfish and circus animals such as camels and elephants. Until the 1880s, when the Mather Stock Car Company and others introduced "more humane" stock cars, loss rates could be quite high as the animals were hauled over long distances.  Improved technology and faster shipping times have greatly reduced losses.

Mater (Cars): Sir Tow Mater, KBE most commonly referred to as Tow Mater or simply Mater is a major character in "Cars" and its sequels, "Cars 2" and "Cars 3" as well as "Cars Toons".  He is voiced by Larry the Cable Guy and inspired by a 1951 International Harvester tow truck.  Portrayed as Lightning McQueen's best friend and sidekick, he had a breakout role in "Cars Toons: Mater's Tall Tales" and in other media related to "Cars".

Lightning McQueen: Lightning McQueen, typically referred to by his surname McQueen, is an anthropomorphic stock car in the animated Pixar film "Cars" (2006), its sequels "Cars 2" (2011), "Cars 3" (2017), and TV shorts known as "Cars Toons."  The character is not named after actor and race driver Steve McQueen, but actually Pixar animator Glenn McQueen, who died in 2002.  His design is inspired by a stock car and "a more curvaceous Le Mans endurance racer," with "some Lola and some Ford GT40."  During the scene where he helps restore Radiator Springs to its 1950s heyday, he is painted much like a 1950's Chevrolet Corvette C1, once again hinting at his Corvette lineage.  His number was originally set to be 57, Lasseter's birth year, but was changed to 95, the release year of Pixar's first film "Toy Story".
