Song of peace

[Joan] Baez took to the stage for about 500 people on an acre lot offered by a landowner who opposes the war, performing such classic peace anthems as "Song of Peace," "Where Have All the Flowers Gone" and "Swing Low, Sweet Chariot."

Here is a verse from 'Where Have All the Flowers Gone':

Where have all the graveyards gone?
Long time passing
Where have all the graveyards gone?
Long time ago
Where have all the graveyards gone?
Covered with flowers every one
When will we ever learn?
When will we ever learn?

When will you?
