Oh bother!! I forgot to put nbsp's between the chords!! Maybe you can work it out; in two or three places a chord or two follows the end of the words - in the gap between the lines, I mean. Sorry for the long delay: the music will follow as soon as I can knock it up.

Second try:

     C                    F
Now he was a Saw Mill proprietor,
   G7         F        G7 C
And she a fair maid yet un_kissed.
                                 F
One evening he winked his squint eye at her,
    G7             Dm        G7 C      G7 C  
But she said "Nay, nay, Sir, de_sist!"
   Em             A dim    Em
So he dragged her into the Saw Mill, poor wench,
Cm   G            D7                G7  Cdim C#dim G7
Then took off his belt and strapped her to   the   bench!

Chorus:
        C                  F
And the great big saw came nearer and nearer
G7                    C
And nearer and nearer and nearer!
                        F
"Be my wife or you will be cut in two!"
         G7                     C
Said the Villain to poor little Vera.
C7  F                              C   F  C  A7
But she said "Nay, nay, though you cut me in twain,
    D7  C7  Ddim D7    Ddim  G    Ddim C#dim G7
The ang_els will stick me to_geth_er   a_____gain!"
        C                  F
And the great big saw came nearer and nearer
G7                    C
and nearer and nearer and nearer!

2.
The villainous Saw Mill proprietor
Heard her screaming there fit to bust,
So what did he do just to quiet her?
He filled up her mouth with saw-dust!
She looked like a lovely wax doll there, it's true,
And chock full of saw-dust she felt like on too!


And the big saw came nearer and nearer!
"Be my wife or you will be cut in two!"
said the Villain to poor little Vera.
But she said "Nay, nay, though you've money in banks
I wouldn't wed you if you cut me in planks!"
And the big saw came nearer and nearer!

       C
But ha ha, look who's here!

Why it's young Rancher Jim!
                                   G7
'Tis her sweetheart, a burly sheep shearer,
       C
And he yells to the Villain "Hands up, you big brute!"
                      G7
And the big saw comes nearer and nearer!
        Em          Am            Em
But the Villain has used his belt strapping her down,
                     Am              Em    Am Em
Yes, he's used it to strap down poor Vera,
                      AM            Em
So when he throws his hands up, his trousers fall down,
                      Am         Em       G7
And the big saw comes nearer and nearer!
