Harris Lloyd "B.B." Seaton (born 3 September 1944, Kingston, Jamaica), also known as "Bibby" is a Jamaican reggae singer and record producer who was a member of The Gaylads, The Astronauts, Conscious Minds, and The Messengers (along with Ken Boothe, Lloyd Charmers, and Busty Brown), and who has had a long solo career which dates back to 1960.

Seaton first recorded as a solo artist in 1960 before forming the duo Winston & Bibby with Winston Delano Stewart. The duo were joined by Maurice Roberts and became The Gaylads, although Seaton soon left to join The Astronauts. Seaton rejoined The Gaylads towards the end of the ska era, and they became hugely successful in Jamaica, and their success continued when they were reduced to a duo after Stewart departed. Seaton left in 1972 and restarted his solo career, having several solo hits the same year with "Accept My Apology", "Sweet Caroline", "Lean on Me", and "Thin Line Between Love and Hate".

Seaton was the first reggae artist to be signed by Virgin Records, leading to the creation of the Front Line label. He became based in the United Kingdom in the mid-1970s where he became active as a producer, his productions including the Gun Court Dub series of dub albums.
