Pete Seeger (1919-2014) proved that there is such a thing and much can be accomplished by it.
I’ve been fortunate to get to know one of Seeger’s many folk offsprings (folksprings?) and glimpse into that dwindling window of that time when idealism seized the form (for a while) of speaking to hearts and minds through lyrics. From The Weavers to the Occupy Movement, Seeger spent his life at the forefront of the most patriotic American tradition: rabble-rousing resistance.
Rouse yourself.
