Collected from Yorkshire (Gomme, 1894, 1898, vol. 2, "The Traditional Games of England, Scotland and Ireland," Ring a Ring o' Roses IV, p. 109.

Ring, a ring o' roses,
A pocket full of posies;
Up-stairs and down-stairs,
In my lady's chamber-
Husher! Husher! Cuckoo!

The year 1502. Rose was having a go with the coachman up in her chambers. All the servants went around saying "Hush! Hush!" but of course the story was repeated in the tavern and the husband heard it. He reported her to the church and town councilors and she was bound for trial. Following conviction for adultry and harlotry, she was condemmed and taken to the town square, where she was burned at the stake.

After that, the last line was changed to "Ashes! Ashes!"
