The folksinger Odetta has passed away. I only got to see her perform live one time. It was back in the first Bush administration. Odetta performed at an outdoor show on the University of Delaware College of Marine Studies campus in Lewes. She introduced the song "Rock-a-Bye Baby" as one that could be sung not only as a lullaby but also as an indictment. And she did so, dedicating the song to, and the indictment against, Bush Sr. It was a memorable show.
