In Evelyn Lord's The Stuart Secret Army: The Hidden History of the English Jacobites he states:
In England folk songs and traditional tunes were borrowed to provide accompaniment for Jacobite songs and ballads and at least one dance tune became synonymous with the Jacobites. John Byrom's journal records that at a ball in Manchester in 1750 "Sir Watkins Jig" was announced. A government officer in the crowd cried out that this was an anti-government and treasonable action as it was written for Sir Watkins Williams Wynn, a well-known Jacobite. This led to a heated argument between Byrom and the officer which developed into a brawl.
It was recorded by Ensemble Galilei on Music in the Great Hall (1992).
