Where Have All The Flowers Gone
Pete Seeger

All acknowledge their debt to Seeger by performing songs or poems he has written or sung over the past half century to champion the labor movement, peace, civil rights, and the environment. Where Have All The Flowers Gone  (wikipedia)

When you bring people together for any reason whatsoever, you're doing politics.

"Now somebody will ask me, Pete, how can you prove these songs really make a
difference? And I have to confess I can't prove a darn thing, except that
the people in power must think they do something, because they keep the
songs off the air." - Pete Seeger

Lyrics:

Where have all the flowers gone, long time passing?
Where have all the flowers gone, long time ago?
Where have all the flowers gone?
Gone to young girls, every one!
When will they ever learn, when will they ever learn?

Where have all the young girls gone, long time passing?
Where have all the young girls gone, long time ago?
Where have all the young girls gone?
Gone to young men, every one!
When will they ever learn, when will they ever learn?

Where have all the young men gone, long time passing?
Where have all the young men gone, long time ago?
Where have all the young men gone?
Gone to soldiers, every one!
When will they ever learn, when will they ever learn?

And where have all the soldiers gone, long time passing?
Where have all the soldiers gone, a long time ago?
Where have all the soldiers gone?
Gone to graveyards, every one!
When will they ever learn, when will they ever learn?

And where have all the graveyards gone, long time passing?
Where have all the graveyards gone, long time ago?
Where have all the graveyards gone?
Gone to flowers, every one!
When will they ever learn, oh when will they ever learn?
