Lancashire has a long and highly productive tradition of music making. In the early modern era the county shared in the national tradition of balladry, including perhaps the finest border ballad, "The Ballad of Chevy Chase", thought to have been composed by the Lancashire-born minstrel Richard Sheale. The county was also a common location for folk songs, including "The Lancashire Miller", "Warrington Ale" and "The soldier's farewell to Manchester", while Liverpool, as a major seaport, was the subject of many sea shanties, including "The Leaving of Liverpool" and "Maggie May", beside several local Wassailing songs. In the Industrial Revolution changing social and economic patterns helped create new traditions and styles of folk song, often linked to migration and patterns of work. These included processional dances, often associated with rushbearing or the Wakes Week festivities, and types of step dance, most famously clog dancing.
