I tried to create this thread a couple of days ago, so apologies if you've seen it before
I am searching for a carol whose first verse is:
Sleep, my darling little son Sleep my lovely, lovely little one For the world is heavy gold For you little hand to hold Sleep, then!
============ Other verses have couplets
You were born to die for we All upon the criss-cross tree
.... you won't mind If we treat you too unkind
I think it is called the 'wormwood carol', but I could be entirely wrong
