Answer the question at the end by quoting:

Ronald Wilson Reagan was born on February 6, 1911 in an apartment on the second floor of a commercial building in Tampico, Illinois. He was the younger son of Nelle Clyde (nee Wilson; 1883-1962) and Jack Reagan (1883-1941). Jack was a salesman and storyteller whose grandparents were Irish Catholic emigrants from County Tipperary, while Nelle was of half English and half Scottish descent (her mother was born in Surrey). Reagan's older brother, Neil Reagan (1908-1996), became an advertising executive.
After graduating from Eureka in 1932, Reagan drove to Iowa, where he held jobs as a radio announcer at several stations. He moved to WHO radio in Des Moines as an announcer for Chicago Cubs baseball games. His specialty was creating play-by-play accounts of games using as his source only basic descriptions that the station received by wire as the games were in progress. While traveling with the Cubs in California in 1937, Reagan took a screen test that led to a seven-year contract with Warner Brothers studios. He spent the first few years of his Hollywood career in the "B film" unit, where, Reagan joked, the producers "didn't want them good; they wanted them Thursday". He earned his first screen credit with a starring role in the 1937 movie Love Is on the Air, and by the end of 1939 he had already appeared in 19 films, including Dark Victory with Bette Davis and Humphrey Bogart. Before the film Santa Fe Trail with Errol Flynn in 1940, he played the role of George "The Gipper" Gipp in the film Knute Rockne, All American; from it, he acquired the lifelong nickname "the Gipper." In 1941, exhibitors voted him the fifth most popular star from the younger generation in Hollywood. Reagan played his favorite acting role in 1942's Kings Row, where he plays a double amputee who recites the line "Where's the rest of me?"--later used as the title of his 1965 autobiography. Many film critics considered Kings Row to be his best movie, though the film was condemned by New York Times critic Bosley Crowther. Although Reagan called Kings Row the film that "made me a star", he was unable to capitalize on his success because he was ordered to active duty with the U.S. Army at San Francisco two months after its release, and never regained "star" status in motion pictures. In the post-war era, after being separated from almost four years of World War II stateside service with the 1st Motion Picture Unit in December 1945, Reagan co-starred in such films as The Voice of the Turtle, John Loves Mary, The Hasty Heart, Bedtime for Bonzo, Cattle Queen of Montana, Tennessee's Partner, Hellcats of the Navy (the only film in which he appears with Nancy Reagan), and the 1964 remake The Killers (his final film). Throughout his film career, Reagan's mother answered much of his fan mail.

What year was this released?

Before the film Santa Fe Trail with Errol Flynn in 1940,

IN: Clarence White (born Clarence Joseph LeBlanc; June 7, 1944 - July 14, 1973), was an American bluegrass and country guitarist and singer. He is best known as a member of the bluegrass ensemble the Kentucky Colonels and the rock band the Byrds, as well as for being a pioneer of the musical genre of country rock during the late 1960s. White also worked extensively as a session musician, appearing on recordings by the Everly Brothers, Joe Cocker, Ricky Nelson, Pat Boone, the Monkees, Randy Newman, Gene Clark, Linda Ronstadt, Arlo Guthrie, and Jackson Browne amongst others. Together with frequent collaborator Gene Parsons, he invented the B-Bender, a guitar accessory that enables a player to mechanically bend the B-string up a whole tone and emulate the sound of a pedal steel guitar.

During 1964, White began to look beyond bluegrass music towards rock 'n' roll as an avenue for artistic expression. Although he was influenced by Country guitarists like Doc Watson, Don Reno and Joe Maphis, he also idolized the playing of jazz guitarist Django Reinhardt, rock 'n' roller Chuck Berry, and studio musician James Burton. White even anticipated the viability of a folk/rock hybrid when, in the summer of 1964, he was approached by Jim Dickson to record a version of the then-unreleased Bob Dylan song "Mr. Tambourine Man" with electric instruments. However, despite White's enthusiasm for the project, he was unable to convince his bandmates in the Kentucky Colonels of the experiment's validity and ultimately, the song was instead recorded by Dickson's proteges, the Byrds. By the time the original line-up of the Kentucky Colonels folded in late 1965, White had become a respected and well-known guitarist. Abandoning bluegrass temporarily, he switched from his Martin D-28 acoustic guitar to an electric Fender Telecaster, with the intention of becoming a studio musician like his hero James Burton. Transitioning to electric guitar required White to modify his right hand playing technique, switch from open chording to fretting the whole guitar neck with his left hand, and practice using the tone and volume controls. However, he soon mastered the intricacies of the instrument and, between 1965 and 1968, he undertook session work for artists including Ricky Nelson, the Monkees, and the Gosdin Brothers. As 1965 turned into 1966, White met Gene Parsons and Gib Guilbeau at a recording session for the Gosdin Brothers and shortly after, he began to perform live with the duo in local California clubs, as well as doing regular session work on their records, which were released under the moniker of Cajun Gib and Gene. 1966 also saw White begin playing with a country group called Trio, which featured drummer Bart Haney and former Kentucky Colonel, Roger Bush, on bass. In autumn of that year, as a result of his friendship with Gilbeau, Parsons and the Gosdin Brothers, White was asked to provide lead guitar to ex-Byrd Gene Clark's debut solo album, Gene Clark with the Gosdin Brothers. White also briefly joined Clark's touring band shortly thereafter. During the Clark album sessions, White reconnected with mandolin player and bassist Chris Hillman, who he had known during the early 1960s as a member of the bluegrass combo the Hillmen. Hillman was currently a member of the Byrds and in December 1966, he invited White to contribute countrified lead guitar playing to his songs "Time Between" and "The Girl with no Name", which both appeared on the Byrds' Younger Than Yesterday album. The country-oriented nature of the songs was something of a stylistic departure for the group and can be seen as an early indicator of the experimentation with country music that would color the Byrds' subsequent work. White also contributed guitar to the band's follow-up album, The Notorious Byrd Brothers, and to their seminal 1968 country rock release, Sweetheart of the Rodeo.
