Get Together by The Youngbloods
If you hear the song I sing,
You must understand
You hold the key to love and fear
All in your trembling hand
Just one key unlocks them both
It’s there at your command
C’mon people now,
Smile on your brother
Ev’rybody get together
Try and love one another right now
I bet there is at least one liberal arts college offering a degree in "Interpretation of 1960's Era Utopian Socialistic Folk Music."
