It's been a long tedious garbage-filled day here, so I'll take my leave
for the nonce with this from The Incredible String Band.

(Yes, the Grateful Dead adopted it later)

Not certain of the exact sources (spirituals, biblical quotes, etc), but
it's OLD!

Lay down my dear sister
Won't you lay and take your rest
Won't you lay your head upon your saviour's breast
And I love you but Jesus loves you the best
And I bid you goodnight, goodnight, goodnight,
And I bid you goodnight, goodnight, goodnight.....

One of these mornings bright and early and fine.
Goodnight, goodnight

Not a cricket not a spirit going to shout me on
Goodnight, goodnight

I go walking in the valley of the shadow of death
Goodnight, goodnight

And his rod and his staff shall comfort me
Goodnight, goodnight

Oh John the wine he saw the sign
Goodnight, goodnight

Oh John say I seen a number of signs
Goodnight, goodnight

Tell A for the ark that wonderful boat
Goodnight, goodnight

You know they built it on the land getting water to float
Goodnight, goodnight

Tell B for the beast at the ending of the wood
Goodnight, goodnight

You know it ate all the children when they wouldn't be good
Goodnight, goodnight

I remember quite well, I remember quite well
Goodnight, goodnight

I was walking in Jerusalem just like John
Goodnight, goodnight, goodnight.......
