Well done.
At youtube, they have that one whole channel for the Vietnam War song project, it appears, they even have a twitter account.
Vietnam War Song Project Twitter Vietnam war song project channel at youtube @Machiavelli I have some favorites but maybe it's best to look on one's own.
I've listened to a lot of the songs, not just the well known songs. It's amazing how many small labels and obscure songs there are. Some pretty good.
