—— folk family and jam

down in yon forest

Down in yon forest there stands a hall
The bells of Paradise I heard them ring
It's covered all over with purple and pall
And I love my Lord Jesus above any thing

In the hall there stands a bed
It's covered all over with scarlet so red

At the foot of the bed there springs a flood
The one half runs water, the other runs blood

By the bed there lies a stone
That the sweet Lady Mary knelt upon

By the bed there grows a thorn
That ever blows blossom since Jesus was born

From Dave

It is a Renaissance carol, deriving from the Corpus Christi carol, the text of which was found in a manuscript from 1509.  
The tune I like.
