My friend the late Fr. Paul Brouillette was huge Seeger fan and fellow banjo player; he once played and sang this in church. He was that kind of guy, and today he welcomes his hero to the celestial jam session.
I once heard a young Occupy Chicago protester sing it via a live Internet feed. Still relevant, still rousing the rabble, Seeger’s passing means the banksters have one less whiny folksinger to criticize them.
