 The Beatles led a movement by various beat groups from the region which culminated in the British Invasion of the US, which in turn made a major contribution to the development of modern rock music.After the decline of beat groups in the late 1960s, the centre of rock culture shifted to London, and there were relatively few Lancashire bands who achieved national prominence until the growth of a disco scene and the punk rock revolution in the mid-and-late 1970s.Lancashire is the origin of the Lancashire hotpot, a casserole dish traditionally made with lamb.
