Artist: Crosby, Stills, Nash and Young [more]
Essence of the music/lyrics: I’ve performed this song 100+ times in front of an audience and I never tire of its message. That is, that learning parents and learning children will always gain from each other’s experience.
Excerpt:
"And so please help them with your youth, they seek the truth before they can die."
