duke street jail

There is a happy land
Down in the Duke Street Jail
Where all the prisoners stand
Tied tae a nail
Ham and eggs they never see
Dirty Water fot their tea
There they live in misery
God Save the Queen

But Glasgae Corporation's come
Up wi' a brand new plan
They're building housing tenements new
Down in that happy land
But there's sixty murderers buried there
So watch yoursel' comin' doon that stair
Or a ghostie'll come and grab you by the hair
God Save the Queen
