<Tr> <Td_colspan="2"> Problems playing this file? See media help . </Td> </Tr> <P> The rhyme is usually sung to a variant of the 1761 French melody Ah! vous dirai - je, maman, which is also used for "Twinkle Twinkle Little Star" and the "Alphabet song". The words and melody were first published together by A.H. Rosewig in (Illustrated National) Nursery Songs and Games, published in Philadelphia in 1879 . </P> <P> As with many nursery rhymes, attempts have been made to find origins and meanings for the rhyme, most which have no corroborating evidence . Katherine Elwes Thomas in The Real Personages of Mother Goose (1930) suggested that the rhyme referred to resentment at the heavy taxation on wool . This has particularly been taken to refer to the medieval English "Great" or "Old Custom" wool tax of 1275, which survived until the fifteenth century . More recently the rhyme has been connected to the slave trade, particularly in the southern United States . This explanation was advanced during debates over political correctness and the use and reform of nursery rhymes in the 1980s, but has no supporting historical evidence . Rather than being negative, the wool of black sheep may have been prized as it could be made into dark cloth without dyeing . </P> <P> A controversy emerged over changing the language of "Baa Baa Black Sheep" in Britain from 1986, because, it was alleged in the popular press, it was seen as racially dubious . This was based only on a rewriting of the rhyme in one private nursery as an exercise for the children there and not on any local government policy . A similar controversy emerged in 1999 when reservations about the rhyme were submitted to Birmingham City Council by a working group on racism in children's resources, which were never approved or implemented . Two private nurseries in Oxfordshire in 2006 altered the song to "Baa Baa Rainbow Sheep", with black being replaced with a variety of other adjectives, like "happy, sad, hopping" and "pink". In 2012, a private nursery in Kingston upon Thames replaced "black" with "little" for their Easter show . Commentators have asserted that these controversies have been exaggerated or distorted by some elements of the press as part of a more general campaign against political correctness . </P>
