Back in around 1986, I was one of a group of fathers who took their sons to a Scout camp on Catalina Island, 20-plus miles off the Los Angeles coast. On the northwestern (the wilder) end of the island, in a canyon on the lee side, we were treated to the comings and goings of feral pigs each night. These were beasts which were once domestic stock but had become wild, once turned loose in open country. Some were pretty surly and bold.

Now, if surly and bold can attach to folk music, I'm all ears! Does the term mean something like "repatriated" or "returned to nature?" Or does it simply mean wild?
