To clear up a few points.
The Imagined Village is about the ideas that underlie the emergence and development of the English Folk Revival. What shaped the proposals that there was a 'Folk' in England and why did people feel their culture was in danger and needed reviving?
I wasn't by any means the first to suggest that the whole concept of the Folk as it came to be presented over time by most Folklorists and then later by Folksong collectors was illogical and bore no relation to the real people who sang, told stories, danced or took part in the customs at the end of the 19th century or into the 20th. The heading of Chapter 1 is a quote taken from Joseph Jacobs (1854-1916) who wrote in 1893 that the Folk was 'a fraud, a delusion, a myth' and simply 'a name for our ignorance'.
Jacob's whole, short article is still relevant today and could potentially reduce the amount of misinformation in some contributions to this discussion.
Also, I've written quite a lot of articles and sleeve notes that engage with the content of songs, but this particular piece of work was about the Folk rather than the specifics of what they sang.
