Joe Offer asked me to post this version from my CD, so here it is. Ironically the closest thing to what we sing was posted by Joe from Scots Songs. By the way, I have only heard this song so I have no idea how to spell any name. "Cosy", "mosy" and "nosy" rhyme with "rosy."Wally" is "wa lee."
Where are you going says cosy mosy?
Where are you going says Jack a thread nosy
Where are you going says brothers all three
I'm going to the woods says willy wally.

What do there?
Going hunting

What are you going to hunt?
Hunting robin redbreast

What are you going to hunt him with?
Bows and arrows

What are you going to cut him up with
knives and hatchets

What are you going to cook him in?
Pots and kettles

Who will help eat him?
My wife and children

Where you throw the bones
I'll throw them in the sea

They'll sink the ships
They'l sink in the sand
