PROBLEM: 'Ring a Ring o' Roses' or 'Ring Around the Rosie' or 'Ring a Ring o' Rosie' is a nursery rhyme or folksong and playground singing game. It first appeared in print in 1881, but it is reported that a version was already being sung to the current tune in the 1790s and similar rhymes are known from across Europe. It has a Roud Folk Song Index number of 7925. Urban legend says the song originally described the plague, specifically the Great Plague of London, or the Black Death, but folklorists reject this idea.
