Yes, I was joking about the Sam Hill being an entrance to Fairyland. Everyone knows, of course, that the entrances to Fairyland, some of them anyhow, are at Tenkiller Lake near Tahlequah, Oklahoma. The Little People live there, in underwater houses accessible through doors in the hillside.

Here is one version of John Barleycorn, although I know of no tradition associating Samhain or Hallowmas with barley-culture.

There came three men from out the west
their victory to try,
and they have taken a solemn oath
John Barleycorn should die.
Sing ri fol lol, the diddle al the dee,
