Actually Steve and EVERYBODY ELSE, Katie took the suggestion of canoer and started a new thread as that one was running its course. She should already have the link to the VietNam thread and she's hoping to get the responses just like you have given. Keeping this to an hour show would be tough.
One that is mentioned several times in other threads was also mentioned by Pete Seeger in a recent special I saw. I found it interesting that Pete Seeger would pick this song from that period but as he said, almost everyone knew the words. "Feel Like I'm Fixin' To Die Rag" by Country Joe MacDonald was pretty well known to say the least.
