To add, for those following the thread, the quote from Roy Palmer is (Everyman's Book of English Country Songs, introduction p3, talking of Henry Burstow):

"Ralph Vaughan Williams visited him in 1904 and took down further songs, some on a recording machine. One hopes that the cylinders, at present preserved at the Institute of Recorded Sound, will one day be transferred to modern records ot tapes, so that we can hear Henry Burstow's voice."
