Many dances were collected by Cecil Sharp and later collectors, and several were included in Bacon's book, but border morris was largely neglected by revival morris sides until late in the 20th century. The Silurian Morris Men of Ledbury, Herefordshire, included border dances in performances from the early 1970s and changed exclusively to border morris in 1979, and the Shropshire Bedlams were founded in 1975; both became pioneers of a resurgence of border morris among revival sides in the following decades.
