Bo Weavil Jackson (dates and places of birth and death unknown, real name said to be James Butler), was an African-American blues singer and guitarist. He was one of the first country bluesmen to be recorded, in 1926, for Paramount Records and Vocalion Records. On the latter label he was credited as Sam Butler, which has become the name most commonly used to identify him. His 78-rpm records are highly sought by collectors and have been re-released on numerous LP and CD compilation albums. His technique is distinctive for its upbeat tempo, varied melodic lines, and impromptu instrumentals.
It is widely believed that Jackson was active in Birmingham, Alabama, because he referred to that area in his lyrics and because that was apparently where the talent scouts found him performing on the street, but he was promoted as originating from North Carolina. According to Eugene Chadbourne, Paramount promoted him as having "come down from the Carolinas". Apart from his 1926 recordings, no further documentation of him exists.
His recordings have been published in both notation and tablature transcriptions, which have enabled contemporary detailed study of his style and technique.
