Question: What do Vernon, Florida and Unchained Memories have in common?
Context: Vernon, Florida is a 1981 documentary film produced and directed by Errol Morris profiling various residents living within the town of Vernon, Florida.  Originally titled "Nub City", this follow-up to "Gates of Heaven" initially focused on residents of the Southern town who cut off their own limbs as a way to collect insurance money.  After Morris's life was threatened by the subjects of the film, he re-worked "Nub City" into "Vernon, Florida". Unchained Memories is a 2003 documentary film about the stories of former slaves interviewed during the 1930s as part of the Federal Writers' Project and preserved in the WPA Slave Narrative Collection.  This HBO film interpretation directed by Ed Bell and Thomas Lennon is a compilation of slave narratives, narrated by actors, emulating the original conversation with the interviewer.  The slave narratives may be the most accurate in terms of the everyday activities of the enslaved, serving as personal memoirs of more than two thousand former slaves.  The documentary depicts the emotions of the slaves and what they endured.  The "Master" had the opportunity to sell, trade, or kill the enslaved, for retribution should one slave not obey. The Mount Vernon Conference was a meeting of delegates from Virginia and Maryland held March 21–28, 1785, to discuss navigational rights in the states' common waterways.  On March 28, 1785, the group drew up a thirteen-point proposal to govern the two states' rights on the Potomac River, Pocomoke River, and Chesapeake Bay.  Known as the Mount Vernon Compact, formally titled as the Compact of 1785, this agreement not only covered tidewater navigation but also extended to issues such as toll duties, commerce regulations, fishing rights, and debt collection.  Ratified by the legislature of both states, the compact helped set a precedent for later meetings between states for discussions into areas of mutual concern. Ellen Call Long (1825-1905) was the daughter of Florida territorial governor Richard Keith Call and a member of the influential Call-Walker political family of Florida.  The longtime proprietor of The Grove, which she acquired from her father in 1851 and held until 1903, Ellen Call Long received distinction after the Civil War through her efforts in historic preservation, history, memorialization, forestry, silkworm cultivation, and the promotion of Florida.  She was the author of Florida Breezes, a semi-fictional account of antebellum life primarily set in Middle Florida which is widely regarded as one of the best primary source accounts of the planter class lifestyle in Florida.  She was the founder of the Florida chapters of the Mount Vernon Ladies Association and the Ladies Hermitage Association.  She was also named a Florida delegate to several important expositions, including the Centennial International Exhibition in Philadelphia (1876), the World’s Columbian Exposition in Chicago (1893), and the Exposition Universelle in Paris, France (1889).  She was the founder of the Ladies Memorial Association of Tallahassee, a group that is now known as the Anna Jackson Chapter of the United Daughters of the Confederacy.  Her published report made before the American Forestry Congress in 1888 titled “Notes of Some of the Forest Features of Florida,” is considered a seminal work in the field of fire ecology.  She was also a tireless promoter of silk culture in Florida, representing the Ladies Silk Culture Association of Philadelphia and emerging as a local expert in cultivation. Juliet Weber is a producer, director, writer, and an editor for the film industry.  She co-produced films such as Fastpitch (2000) and Unchained Memories (2003). The Battle of Vernon, Florida was a minor skirmish of the American Civil War that took place on September 28, 1864, near the town of Vernon, Florida.  Coming a day after the larger Battle of Marianna, this conflict involved a company of Home Guard troops from Vernon who were going to the aid of their Confederate compatriots in that city.  Unbeknownst to the Southerners, their route had taken them straight toward the withdrawing Federal column under Brigadier General Alexander Asboth, which was returning to their main base at Pensacola after their victory at Marianna.  The two forces met on a wooden bridge across Hard Labor Creek in Washington County; refusing to heed Union demands to disperse, the badly-outnumnered Floridians chose to resist and were quickly defeated, with most of them being taken prisoner. Ship of Memories is a compilation album from the Dutch rock band Focus, released in 1976 on EMI-Bovema.  During a period of group inactivity, longtime associate Hubert Terheggen asked their producer Mike Vernon to select previously unreleased material for official release.  The recordings, chosen without any active involvement with either band member, date from January 1970 to mid-1975, largely during unproductive recording sessions in 1973 for a follow up studio album to "Focus 3" (1972). The Story of Vernon and Irene Castle is an American biographical musical comedy, released in 1939 and directed by H.C. Potter.  The film stars Fred Astaire, Ginger Rogers, Edna May Oliver, and Walter Brennan.  The movie is based on the stories "My Husband" and "My Memories of Vernon Castle", by Irene Castle.  The movie was adapted by Oscar Hammerstein II, Dorothy Yost and Richard Sherman. Olfactory memory refers to the recollection of odors. Studies have found various characteristics of common memories of odor memory including persistence and high resistance to interference.  Explicit memory is typically the form focused on in the studies of olfactory memory, though implicit forms of memory certainly supply distinct contributions to the understanding of odors and memories of them.  Research has demonstrated that the changes to the olfactory bulb and main olfactory system following birth are extremely important and influential for maternal behavior.  Mammalian olfactory cues play an important role in the coordination of the mother infant bond, and the following normal development of the offspring.  Maternal breast odors are individually distinctive, and provide a basis for recognition of the mother by her offspring. "The 6th Sense" is the first single from Common's 2000 album "Like Water for Chocolate" and is a b-side of "The Light."  It is produced by DJ Premier making it the only song on Common's 2000 album not produced by a member of the Soulquarians.  It features Premier's trademark chorus with scratched samples; the samples are from "Memories Are Here to Stay" by The Intruders and "Allustrious" by Mobb Deep.  The chorus also features singing by neo-soul artist Bilal.  The song's lyrics discuss afrocentricity, hip hop culture and various social issues.  "The 6th Sense" begins with an introduction in which Common states "the revolution will not be televised, the revolution is here" referencing the famous Gil-Scott Heron song named "The Revolution Will Not Be Televised."
