"According to one source the words "lillibulero" and "bullen al-a" were used as a rallying cry for the Irish to recognize one another in the uprising in 1641. Later (1687) Thomas, Lord Wharton (1640-1715), wrote a set of satirical verses titled Lillibolero regarding the Irish problems and set them to a melody arranged by Henry Purcell in 1678. Purcell's arrangement was based on an older tune under the name Quickstep which appeared in Robert Carr's Delightful Companion (1686). It became popular immediately. After the Stuarts were deposed, Lord Wharton, a strong supporter of William III, boasted that he had "rhymed James out of three kingdoms" with his tune".
