Robert Dwayne Womack was an American singer, musician and songwriter. Starting in the early 1950s as the lead singer of his family musical group the Valentinos and as Sam Cooke's backing guitarist, Womack's career spanned more than 60 years and multiple styles, including R&B, jazz, soul, rock and roll, doo-wop, and gospel.

Samuel Cooke, known professionally as Sam Cooke, was an American singer and songwriter. Considered one of the most influential soul artists of all time, Cooke is commonly referred to as the "King of Soul" for his distinctive vocals, pioneering contributions to the genre, and significance in popular music. During his eight-year career, Cooke released 29 singles that charted in the Top 40 of the Billboard Pop Singles chart, as well as 20 singles in the Top Ten of Billboard's Black Singles chart. In 1964, Cooke was shot and killed by the manager of a motel in Los Angeles. After an inquest and investigation, the courts ruled Cooke's death to be a justifiable homicide. His family has since questioned the circumstances of his death. Cooke is included on Billboard's 2015 list of the 35 greatest R&B artists of all time.
