This song is in the DT and the chorus goes:

I want a proper cup o'coffee
Made in a proper copper coffee pot
I must be off my dot
to want a cup o' coffee
in a propere coffee Pot
Brown coffee pots and green coffee pots
They're no use to me right OY
If I can't have a proper cup o' coffee from a proper copper coffee pot I'll have a cup o' tea.
