It was Johnny Cash's birthday yesterday. Here is one of my favorite Youtube clips, filmed when he came out against the Vietnam war before a college audience in 1971. The students are respectful & quiet at the beginning, then erupt in applause as it's clear he's against the war. Note the smiling, yet tear-filled, woman near the end. As the old Irish ballad says, 'Johnny, we hardly knew ya'. He receives a standing ovation.
