History of Morris Dancing
Most of us dance not just because Morris is historical, but because it's fun. But the historical connection is certainly interesting. Some years ago I picked up Keith Chandler's book Ribbons, Bells and Squeaking Fiddles - a social history of morris dancing from 1660 - 1900. 
it's well worth getting a copy of this, or at least one for your side - it's now available on a CD-ROM along with some other work he's done on stats on sides over the years.
It's available from the Musical Traditions website:
