I'm seeking the words to "Sleepers Awake". It's an "Incedible String Band" song from about 35 years ago. Its title comes up on several of the band's sites but the lyrics don't seem to be available anywhere. Don't know if the melody comes from the Bach piece of the same name but I know the melody for the song I want.
Here's what I know:

Sleepers awake for the night has gone and taken
Your (?)gravest fears and left us here
Awake for the dawn (?morn)is wonderful

That's all I have. Tantalizing isn't it?
Can anyone help please?
Thanks. Cheers, Joy
