Eddie Jefferson was an American jazz vocalist and lyricist. He is credited as an innovator of vocalese, a musical style in which lyrics are set to an instrumental composition or solo. Jefferson himself claims that his main influence was Leo Watson. Perhaps Jefferson's best-known song is "Moody's Mood for Love" which was recorded in 1952, though two years later a recording by King Pleasure catapulted the contrafact into wide popularity. Jefferson's recordings of Charlie Parker's "Parker's Mood" and Horace Silver's "Filthy McNasty" were also hits.

Richie Cole was an American jazz saxophonist, composer, and arranger.
