Eddie Jefferson (3 August 1918 - 9 May 1979) was a jazz vocalist and the founder of vocalese, where a singer sings words to a famous instrumental solo. His best known composition is "Moody's Mood for Love" though it was recorded first by King Pleasure, who cites Jefferson as an influence. His songs "Parker's Mood" and "Filthy McNasty" were also hits.
Jefferson's last recorded performance was at the Joe Segal's Jazz Showcase in Chicago. His band at that performance was Richie Cole (alto sax), John Campbell (piano), Kelly Sill (bass) and Joel Spencer (drums).
