Jack Leroy "Jackie" Wilson, Jr. (June 9, 1934 - January 21, 1984) was an American singer. Wilson was important in the transition of rhythm and blues into soul. Gaining fame in his early years as a member of the R&B vocal group, The Dominoes, after going solo in 1957, he went on to record over fifty hit singles over a repertoire that included R&B, pop, soul, doo-wop and easy listening before lapsing into a coma following a collapse on stage during a 1975 benefit concert. By the time of his death in 1984, he had become one of the most influential soul artists of his generation
