A blog entry today on meetwithcindy.org outlines the entertainment schedule at Camp Casey outside the president’s Texas ranch:

James McMurtry, a political/folk/rock singer came to Camp Casey last night to entertain the troops. Steve Earle followed, singing “Rich Man’s War” along with other favorites. Hey, we sit in ditches all day, it’s nice to have a little entertainment once in awhile! Speaking of entertainment, check back here tonight for an update on this evening’s performer — nothing says “Peace Movement” like she does.

And we now know that that performer was…Joan Baez. “In the first march I went to (opposing Vietnam) there were 10 of us,” Baez told the crowd, according to the Associated Press. “This is huge.”
