I tried to contact Professor Sephten Sprake here at the Open University (he is Course Director for A371: Folk Music and the Lower Orders, 1830-1900), but he's doing a stint as Ethno-musicologist In Residence at HMP Bedford until Christmas. But Prof Sprake's secretary looked up the blue clicky, and said "How much credence should we give to a man with name like 'Brett Shatner'?"
