Some context: Exile, originally known as The Exiles, is an American band founded in Richmond, Kentucky, by J.P. Pennington. They started by playing local clubs which led to touring with Dick Clark's Caravan of Stars opening shows and providing backup for major rock artists of the period. Their name was shortened to Exile in 1973, consisting of guitarist Pennington, leader/lead singer Jimmy Stokley, Bernie Faulkner B3 sax acoustic guitar, Billy Luxon trumpet, keyboardist Buzz Cornelison, bassist Kenny Weir, and drummer Bobby Johns.
In 1963, a group of high school students started a rock and roll band in Richmond, Kentucky. They called themselves the Exiles. Those original Richmond Exiles were Jimmy Stokley, Ronnie 'Mack' Davenport, Paul Smith, Mike Howard, Billy Luxon, J.P. Pennington, and Buzz Cornelison. Richmond native Danny Williams was also a member in the 1960s. Their chosen name may have resulted from the influx of Cubans into the United States after the Fidel Castro takeover in 1959. According to original Exile Pennington, "There were a lot of Cuban exiles coming across...the word was in the news and we felt we were also somewhat ostracized from the local society. We had long hair back then..."  Most of the Exiles were students at Madison Central and Madison High School in Richmond when the band formed and played together from 1963 to 1965. They were an offshoot of Ronnie (Hall) and the Fascinations. They were briefly known in those early years as Jimmy Stokley and the Exiles. Stokley (18 October 1943 - 13 August 1985) was the lead singer of the group and continued in that capacity until 1979. It is Stokley's lead voice that is prominent on Exile's 1978 Billboard pop music chart-topper, "Kiss You All Over".  When the Dick Clark Caravan Of Stars hit the road in 1965, they picked up the Exiles to perform on several dates in and around Kentucky. They continued touring nationally with the Caravan of Stars through to 1968; opening the show and providing back-up for headlining stars like Freddy Cannon, B. J. Thomas, Paul Revere and the Raiders and others.  In the early 1960s the Exiles recorded their first record in the studios of WEKY Radio Station in Richmond. Side one was named "The Answer to Her Prayers" written by Paul Smith, Jr. and the back side was called "Come On". The recording was produced by WEKY Radio DJ" Jimmy K" (Kincer) on his own record label "JIMBO Records". In the late 1960s, they recorded for both Date Records and Columbia Records, and in the early 1970s for SSS International, Date, Curb and Wooden Nickel record labels. With the help of Cecil Jones of Lemco Sound Studios in Lexington, the Exiles developed and polished their sound. The band scored regional hits such as "Devil's Bite" and "Church Street Soul Revival" (written and produced by Tommy James).
Why did they record for both?
A: the Exiles developed and polished their sound.
Some context: Manorialism was an essential element of feudal society. It was the organizing principle of rural economy that originated in the Roman villa system of the Late Roman Empire, and was widely practiced in medieval western and parts of central Europe. It was slowly replaced by the advent of a money-based market economy and new forms of agrarian contract. Manorialism was characterised by the vesting of legal and economic power in a Lord of the Manor, supported economically from his own direct landholding in a manor (sometimes called a fief), and from the obligatory contributions of a legally subject part of the peasant population under the jurisdiction of himself and his manorial court.
The term is most often used with reference to medieval Western Europe. Antecedents of the system can be traced to the rural economy of the later Roman Empire (Dominate). With a declining birthrate and population, labor was the key factor of production. Successive administrations tried to stabilise the imperial economy by freezing the social structure into place: sons were to succeed their fathers in their trade, councilors were forbidden to resign, and coloni, the cultivators of land, were not to move from the land they were attached to. The workers of the land were on their way to becoming serfs.  Several factors conspired to merge the status of former slaves and former free farmers into a dependent class of such coloni: it was possible to be described as servus et colonus, "both slave and colonus". Laws of Constantine I around 325 both reinforced the semi-servile status of the coloni and limited their rights to sue in the courts; the Codex Theodosianus promulgated under Theodosius II extended these restrictions. The legal status of adscripti, "bound to the soil", contrasted with barbarian foederati, who were permitted to settle within the imperial boundaries, remaining subject to their own traditional law.  As the Germanic kingdoms succeeded Roman authority in the West in the fifth century, Roman landlords were often simply replaced by Germanic ones, with little change to the underlying situation or displacement of populations.  The process of rural self-sufficiency was given an abrupt boost in the eighth century, when normal trade in the Mediterranean Sea was disrupted. The thesis put forward by Henri Pirenne, while disputed widely, supposes that the Arab conquests forced the medieval economy into even greater ruralization and gave rise to the classic feudal pattern of varying degrees of servile peasantry underpinning a hierarchy of localised power centers.
How much of society was involved in manorialism?
A: it was possible to be described as servus et colonus, "both slave and colonus".
Some context: James was born in Holton, Kansas; his mother, died in 1954 when he was five. His father was a janitor and a handyman. After four years at the University of Kansas residing at Stephenson Scholarship hall, James joined the Army in 1971. He was the last person in Kansas to be sent to fight in the Vietnam War, although he never saw action there.
An aspiring writer and obsessive fan, James began writing baseball articles after leaving the United States Army in his mid-twenties. Many of his first baseball writings came while he was doing night shifts as a security guard at the Stokely-Van Camp's pork and beans cannery. Unlike most writers, his pieces did not recount games in epic terms or offer insights gleaned from interviews with players. A typical James piece posed a question (e.g., "Which pitchers and catchers allow runners to steal the most bases?"), and then presented data and analysis written in a lively, insightful, and witty style that offered an answer.  Editors considered James's pieces so unusual that few believed them suitable for their readers. In an effort to reach a wider audience, James began self-publishing an annual book titled The Bill James Baseball Abstract beginning in 1977. The first edition, titled 1977 Baseball Abstract: Featuring 18 categories of statistical information that you just can't find anywhere else, presented 68 pages of in-depth statistics compiled from James's study of box scores from the preceding season and was offered for sale through a small advertisement in The Sporting News. Seventy-five people purchased the booklet. The 1978 edition, subtitled The 2nd annual edition of baseball's most informative and imaginative review, sold 250 copies. Beginning in 1979, James wrote an annual preview of the baseball season for Esquire, and continued to do so through 1984.  The first three editions of the Baseball Abstract garnered respect for James's work, including a very favorable review by Daniel Okrent in Sports Illustrated. New annual editions added essays on teams and players. By 1982 sales had increased tenfold, and a media conglomerate agreed to publish and distribute future editions.  While writers had published books about baseball statistics before (most notably Earnshaw Cook's Percentage Baseball, in the 1960s), few had ever reached a mass audience. Attempts to imitate James's work spawned a flood of books and articles that continues to this day.
Did other writer reach a mass audience after him?
