Readers who want to sample the musical performances available at the anti-Bush protest in Texas can try here, for a recording of Joan Baez singing “Where Have All The Flowers Gone?” or here, for a video of Steve Earle singing “The Revolution Starts Now.” Readers may note that the Washington Post’s Mike Allen reported this morning that Camp Casey sports a new venue — “a party tent for 2,000,” Allen called it — but judging from the crowd in the Earle video, there were a number of empty seats.
