I have always liked a lot of Tom Paxton's work. This, despite the fact that he's an addle-brained leftist and that I personally saw him sign a petition in support of the IRA when I was a naieve youth waiting backstage for his autograph at the no-longer-with-us Free Trade Hall in Manchester. Those were the days when he could still fill such a venue.
This piece (a free download from his website, where you can find many other of what he calls his "short shelf-life songs") is a rehash of his Vietnam classic Lyndon Johnson told the Nation.
It pains me to say that it works pretty well, as unfair as it is.
