In an interview several years ago with Charlie Rose, Seeger said it's often easier to say tough things in a song than in simple direct speech. He often used music to say tough things that needed to be said.
I grew up with his music, but never thought of him as more than a folksinger until I saw a PBS American Masters show about him. That's when I came to appreciate what he did for us -- not only penning so many memorable songs, but standing up and fighting for so many things we now hold dear.
Pete Seeger died last night at age 94.
