"Singing 'Blowin' in the Wind' all the places we've been, it takes on a different meaning everywhere.
When you sing the line, 'How many years can a people exist, before they're allowed to be free?' in a prison yard for political prisoners in El Salvador; if you have sung it to a group of union organizers, who have all been in jail, in South Korea; if you've sung to Jews in the Soviet Union who have been refused exit visas; if you've sung it with Bishop Tutu protesting apartheid, the song breathes, it lives, it has a contemporary currency."
