The key

It's just one thing baby I'm asking you to do
It's just one little thing baby I'm asking you to do
Please give me back your key to your door

I called the little girl about a quarter after nine
I called the little girl one morning about a quarter after nine
The landlady say: I'm sorry, she's not in at the present time

I called my baby back about fifteen after four
I called my baby back fifteen after four
I said darling, would you please give me back the key to your door?
