Background: Joe Jackson Gibbs (born November 25, 1940) is a former American football coach, current NASCAR Championship team owner, and former NHRA team owner. He was the 20th and 26th head coach in the history of the Washington Redskins (1981-1992, 2004-2007). Well known for his long hours and work ethic, Gibbs constructed what Steve Sabol has called, "The most diverse dynasty in NFL history", building championship teams with many players who have had mediocre to average careers while playing for other NFL teams. During his first stint in the National Football League, he coached the Redskins for 12 seasons and led them to eight playoff appearances, four NFC Championship titles, and three Super Bowl titles.
Context: Although Gibbs helped craft a passing-oriented attack during his time in San Diego, his Redskins teams were known to incorporate a smash-mouth, rushing-oriented attack like the counter trey. By building a strong offensive line (known as "The Hogs") Gibbs was able to control the line of scrimmage, allowing workhorse running backs such as John Riggins, George Rogers, and Earnest Byner to power the ground game. Gibbs added a deep passing attack to this which complemented the ground game, utilizing agile receivers such as Art Monk, Gary Clark, and Ricky Sanders. Gibbs' offense was aided during his tenure by aggressive defensive units under the direction of defensive coordinator Richie Petitbon.  Gibbs' system and offensive scheme were robust enough to be successful without a Hall-of-Fame-caliber quarterback at the helm. The Redskins' Super Bowl victories were won featuring Joe Theismann, Doug Williams, and Mark Rypien--capable players who were very successful along with their strong supporting cast.  Gibbs is credited with inventing the single back, double or triple tight end set. He used it to neutralize Hall of Fame linebacker Lawrence Taylor, realizing that to successfully block him with a running back was impossible; an extra tight end and a tackle were required as well. The extra tight end provided additional protection for the quarterback. Gibbs was also credited for creating the Trips formation; stacking three wide receivers to one side. Gibbs incorporated the shifting and motions for which his offenses were known. The formations created mismatches and confusion for the opposing defenses that would then be exploited. He is also one of few coaches that utilized the H-back position prominently in his offense.

Background: Joe Tex was born Joseph Arrington, Jr. in Rogers, Texas, in Bell County to Joseph Arrington and Cherie Sue (Jackson) Arrington. He and his sister Mary Sue were initially raised by their grandmother, Mary Richardson. After their parents divorced, Cheri Arrington moved to Baytown. Tex played baritone saxophone in the high-school band and sang in a local Pentecostal church choir.
Context: Tex recorded for King Records between 1955 and 1957 with little success. He later claimed he sold musical rights to the composition "Fever" to King Records staff, to get money to pay his rent. The song's credited songwriters, Otis Blackwell (who used the pseudonym John Davenport) and Joe Cooley, disputed Tex's claims. Labelmate Little Willie John had a hit with "Fever", which inspired Tex to write the first of his answer songs, "Pneumonia".  In 1958, he signed with Ace and continued to have relative failures, but he was starting to build a unique stage reputation, opening for artists such as Jackie Wilson, James Brown, and Little Richard. He perfected the microphone tricks and dance moves that defined the rest of his career. Many, including Little Richard, claim that Tex's future nemesis James Brown stole Tex's dance moves and microphone tricks. In 1960, he left Ace and briefly recorded for Detroit's Anna Records label, where he scored a Bubbling Under Billboard hit with his cover version of Etta James' "All I Could Do Was Cry". By then, Tex's use of rapping over his music was starting to become commonplace.  In 1961, he recorded his composition "Baby You're Right" for Anna. Later that year, James Brown recorded a cover version, though with different lyrics and a different musical composition, gaining songwriting credit, making it a hit in 1962, and reaching number two on the R&B chart. During this time, Tex first began working with Buddy Killen, who formed the Dial Records label behind Tex. After a number of songs failed to chart, Killen decided to have Atlantic Records distribute his recordings with Dial in 1964. By the time he signed with Atlantic, Tex had recorded 30 songs, all of which had failed to make an impact on the charts.
Question: did he write his own music or he sung other's songs?

He perfected the microphone tricks and dance moves that defined the rest of his career. Many, including Little Richard,
