From the wiki: “‘Stir It Up’ was written by Bob Marley in 1967, for his wife Rita, and was first recorded and released the same year by The Wailers. Following Marley’s return to Jamaica from the United States in 1967, the Wailers started their own label, Wail’n Soul’m Records, and released their first independent single, ‘Freedom Time’. ‘Nice Time’, ‘Thank You Lord’, and ‘Stir It Up’ (backed with ‘The Train’) were all recorded in the same year. The label folded shortly after, after which Marley began writing for American singer Johnny Nash. Nash used members of The Wailers and recorded several Marley songs on his 1972 album, I Can See Clearly Now, including ‘Stir It Up’.
