These words are different enough from those posted by Jim McLean above, that I think it's worthwhile posting them. My transcription:

LADY CHAT
Words by Jim McLean, music traditional "Take a Whiff on Me"
As recorded by Matt McGinn on "The Best of Matt McGinn, Vol. 2" (2003)

1. Have ye heard of Lady Chatterley?
Sick and starved of love was she.
Hey, hey! Puir wee Lady Chat!
Rat-a-tat-a-tat-a-tat.

2. Good Sir Clifford was her man.
He got shot in the war and he couldnae stand.
Hey, hey! Puir wee Lady Chat!
Rat-a-tat-a-tat-a-tat.

3. Gamekeeper Mellors was a crook.
I think he had read the book.
Oh, ho! Watch out, Lady Chat!
Rat-a-tat-a-tat-a-tat.

4. Lady Chat was full o' pluck.
She went tae the garden to try her luck.
Oh, ho! Fly, wee Lady Chat!
Rat-a-tat-a-tat-a-tat.

5. She gave three knocks and a rat-a-tat-tat,
'Come in,' says he, 'and we'll hae a wee chat.'
Oh, ho! Watch out, Lady Chat!
Rat-a-tat-a-tat-a-tat.

6. He took her on his knee and then
Ye can read what he did on page a hundred and ten.
Oh, ho! Bad wee Lady Chat.
Rat-a-tat-a-tat-a-tat.

7. When Sir Clifford o' this heard,
He called his wife a four-letter word.
Ha, ha! Bad wee Lady Chat!
Rat-a-tat-a-tat-a-tat.

8. Tae all you lords, this moral I'll tell:
If you have a wee garden, dig it yoursel'.
Oh, ho! That was the end o' that.
Rat-a-tat-a-tat-a-tat.
