In 1969 (yeah, I'm old) the Youngbloods released "Get Together", but if you bought the 45 (single), the song was backed with "Darkness, Darkness"
Darkness, darkness be my pillow
Take my hand and let me sleep
In the coolness of your shadow in the silence of your deed
Darkness darkness be my blanket
Take my hand and let me sleep
Take away take away the pain that won't go away
Cover me in your night
