This next one smacked me right in the face, and immediately had me looking up who Dave Van Ronk was. He was an American folk singer from Brooklyn and a big-time presence in Greenwich Village back in the day. This one is done to the tune of Byker Hill, an English folk song about coal miners. He updated it for the Vietnam War and Patrick Sky originally recorded it. Here is his version. Wow. "...and now I'm a fucking hero."
