Pete's 4th verse is in his book "Where Have All The Flowers Gone?" published by Sing Out!, in the "New Words…" chapter.
Daughter, Daughter, don't you know
You're not the first to feel just so,
But let me say before I go,
It's worth it anyway.
Some day we may all be surprised,
We'll wake and open up our eyes,
And then we all will realize
The whole world feels this way.
We've all been living upside down,
And turned around with love unfound,
Until we turn and face the sun;
Yes, all of us, everyone.
