t's in the DT, of course, with midi: BUSHES AND BRIARS: as noted by Ralph Vaughan Williams from Charles Pottipher of Ingrave, Essex, in December 1903. It wasn't a chance overhearing, as the DT notes suggest; Vaughan Williams had been specifically invited by the local Vicar's daughters to attend an old people's tea-party their father was giving, so that he could meet some real traditional singers. In fact, he only noted the first verse of Bushes and Briars from Mr. Pottipher, being then new to song-collecting, and later got the rest of the words from a broadside published by Fortey of Seven Dials.
Several broadside editions can be seen at Bodleian Library Broadside Ballads. For example:
