Had to add one of my favorites from the time. Dave Van Ronk's "Romping Through The Swamp." URL follows. I first heard this about three years after my Dad returned from his one year tour for the Air Force building the radar station on Monkey Mountain, several miles north of Danang. It was a great favorite of snipers and got him his second Air Force Commendation Medal award (at least the bullet missed him by a few inches, have slides of him pointing at the hole and Westmoreland dropping by.) They also had a great view of the real "China Beach" as they coined it where they used to occasionally swim, when they were able to get a Huey for shark patrol.
He also did a year over N Korea as bombardier in a B-29 and was an original member of the 36th Artillery Regiment, the third most decorated regiment in all of WW II. He was a loader in the Mutzig Castle direct fire incident. I only learned about the Korea and World War II part starting 10 years after he passed. He was one of those heroes who never spoke about it and perhaps, unfortunately, never realized it.
Bless all of those unsung heroes.
