Art,
I don't think Pete Seeger has done anything in his life I would classify as "glib " or of a "quickie bumper-sticker" nature. I may have misunderstood what exactly you were looking for, but Pete's words have had a great impact on my life.
When I first deciphered what Pete had written on the face of his banjo, it wasn't a solution to an immediate crisis as much as a validation of my life.
Those few words convey the power of folk music, nonviolence, and activism more clearly to me than almost anything else I have encountered.
Peace my friend.... Mike
