Jack Leroy Wilson Jr. (June 9, 1934 – January 21, 1984) was an American singer who was a prominent figure in the transition of rhythm and blues into soul. Nicknamed "Mr. Excitement", he was considered a master showman and one of the most dynamic singers and performers in the 20th century. Among his hits are "Lonely Teardrops," "Baby Workout," "Reet Petite", "I Get the Sweetest Feeling" and "(Your Love Keeps Lifting Me) Higher and Higher". His performance style is often cited as a significant influence on contemporary and later artists such as Elvis Presley, James Brown, and Michael Jackson.
Born in the Detroit enclave of Highland Park, Michigan, Wilson initially gained fame as a member of the R&B vocal group Billy Ward and His Dominoes. He went solo in 1957 and scored more than 50 chart singles spanning the genres of R&B, rock 'n' roll, soul, doo-wop and easy listening. This included 16 top-10 R&B hits, six of which ranked as number ones. On the Billboard Hot 100, Wilson scored 14 top-20 pop hits, six of which reached the top 10.
