input: The Clark Sisters were born and raised in Detroit, Michigan. They each began singing at an early age, and by the late 1960s they were all performing together in church services, usually singing songs written and arranged by their mother. A few years later, Dr. Mattie Moss Clark turned over control of the group to Twinkie, who would then go on to write, arrange, conduct, and produce all of the Clark Sisters' recordings. In 1973, the sisters recorded their first album, Jesus Has A Lot To Give, on their uncle's local label Billesse Records. The following year, Dr. Mattie Moss Clark Presents The Clark Sisters was released and people around Detroit began to take notice of the group. The Clark Sisters signed to Sound of Gospel Records in 1974. Under this association, the group released albums such as Unworthy, Count It All Joy, and He Gave Me Nothing to Lose. It was not until the early 1980s that The Clark Sisters began to become more widely known. Their popularity soared with the release of the live recording Is My Living In Vain. The first live recording by The Clark Sisters spent an entire year at number one on Billboard's Gospel Music chart. Opening with the bluesy title track, each sister vocally declares that their dedication to Christ is not a useless effort. The innovative "Hi ya" was funky enough to find its way into a Tonex produced track over two decades later. Karen Clark's lead on "Speak Lord" expresses deep faith while the call to worship is raised on "Now Is The Time". Another hit from this release, "Expect Your Miracle", is still a staple in black churches across the country. Their next release You Brought the Sunshine would prove to be a monster hit via the title track. Reminiscent of Stevie Wonder's "Master Blaster (Jammin')," the song became a hit in church houses and on dance floors, including New York's Studio 54. "Sunshine" was picked up from its original independent gospel record label Sounds of Gospel and distributed by both Westbound Records and Elektra Records. In 1983, the song peaked at #16 on the Black Singles chart, #27 on the Club Play Charts, and #80 on the Hot R&B Charts driving the album to Gold sales. This album continues to display Twinkie's signature blend of scripture with unprecedented vocal and musical arrangements on biblically based songs like "Psalms 31." The album's other songs include the sincere prayer found within the lyrics of both "Center of Thy Will" and "Endow Me," featuring a young but already vocally mature Karen, as well as "Overdose of the Holy Ghost", showcasing Dorinda's vocal dexterity. The disco-inspired "He Keeps Me Company" is noted for its bubbly syncopation. The sisters delivered another progressive effort in 1982, Sincerely, which included "Name It And Claim It" and the politically charged "World." Though its success was overshadowed by the previous hit "You Brought The Sunshine", the album received a Grammy nomination.

Question: Robert Ervin Howard (January 22, 1906 - June 11, 1936) was an American author who wrote pulp fiction in a diverse range of genres. He is well known for his character Conan the Barbarian and is regarded as the father of the sword and sorcery subgenre. Howard was born and raised in Texas. He spent most of his life in the town of Cross Plains, with some time spent in nearby Brownwood.

Howard was born January 22, 1906 in Peaster, Texas, the only son of a traveling country physician, Dr. Isaac Mordecai Howard, and his wife, Hester Jane Ervin Howard. His early life was spent wandering through a variety of Texas cowtowns and boomtowns: Dark Valley (1906), Seminole (1908), Bronte (1909), Poteet (1910), Oran (1912), Wichita Falls (1913), Bagwell (1913), Cross Cut (1915), and Burkett (1917). During Howard's youth his parents' relationship began to break down. The Howard family had problems with money which may have been exacerbated by Isaac Howard investing in get-rich-quick schemes. Hester Howard, meanwhile, came to believe that she had married below herself. Soon the pair were actively fighting. Hester did not want Isaac to have anything to do with their son. She had a particularly strong influence on her son's intellectual growth. She had spent her early years helping a variety of sick relatives, contracting tuberculosis in the process. She instilled in her son a deep love of poetry and literature, recited verse daily and supported him unceasingly in his efforts to write. Other experiences would later seep into his prose. Although he loved reading and learning, he found school to be confining and began to hate having anyone in authority over him. Experiences watching and confronting bullies revealed the omnipresence of evil and enemies in the world, and taught him the value of physical strength and violence. Being the son of the local doctor gave Howard frequent exposure to the effects of injury and violence, due to accidents on farms and oil fields combined with the massive increase in crime that came with the oil boom. Firsthand tales of gunfights, lynchings, feuds, and Indian raids developed his distinctly Texan, hardboiled outlook on the world. Sports, especially boxing, became a passionate preoccupation. At the time, boxing was the most popular sport in the country, with a cultural influence far in excess of what it is today. James J. Jeffries, Jack Johnson, Bob Fitzsimmons, and later Jack Dempsey were the names that inspired during those years, and he grew up a lover of all contests of violent, masculine struggle.
