Free tribute concert at Lincoln Center going on now- I imagine Lincoln Center will continue to keep the video up at lincolncenter.org.
His kids and grandkids insisted the concerts in his honor be free because they said Pete Seeger would have not have approved of it otherwise.
Best quip about him I heard- his wife, before she passed away, was quoted as saying, "If Pete would just chase women instead of causes I'd have an excuse to leave him." Hee hee.
EDIT: Full concert available on seegerfest.org
