Bob Pegg's "MR. FOX" Lyric is:

MR. FOX
(Bob Pegg)

I'll tell you a tale of Mr. Fox, how he came courting me.
He was the smartest fellow a girl could hope to see.
Foxy came to our town in the springtime of the year
And said I was the fairest of any young girl here.

My Dad said I should marry him, and I should be his bride,
And I saw me walking up the aisle with Foxy by my side.
But I didn't trust old Mr. Fox and I didn't trust his smile,
So I told him hold the wedding day and put it by awhile.

This didn't suit old Mr. Fox. He said I'd rue the day.
He pulled his hat down over his eyes and went upon his way.
But unbeknownst to Foxy, I followed through the wood
Till I came across the clearing where his fine old mansion stood.

I hadn't been there but awhile when I heard a scream and shout.
It was Foxy with a woman a-knocking her about.
I hadn't been there but awhile when I heard a person swear.
It was Foxy with a woman, held fast by the hair.

He dragged her through the bushes. He dragged her through the trees.
It tore my heart in two to see her pleading on her knees.
He dragged her up the marble steps. He dragged her through the hall.
I followed close behind him and stood against the wall.

As they were going up the stair, the woman gave a wail.
She tore away from Fox and clasped her hand upon a rail.
Foxy took his knife. With a blow both sharp and sweet
The hand was severed from the wrist and dropped down at my feet.

The night was cold. The night was dark. No comfort could I find.
I ran through the trees as if the devil was behind.
The forest it was dark and thick and I was pricked with many a thorn,
But I ran through the trees as if I'd never see the dawn.

The very next day old Foxy came to see if we'd be wed.
I told that I had a dream as I lay in my bed.
I told him that I'd seen a house in the middle of the wood
And anyone who went inside, would never come to good.

Foxy turned his back on me. He turned as if to leave.
I pulled him by the arm and took the hand from out my sleeve.
Foxy gave a yelp and then he gave a squeal
And ran as if the hounds of hell were crying at his heel.

In the middle of the forest where the lark and linnet sing,
The dogs of the town got Fox inside a ring.
They tore him limb from limb. They tore him hair from hair,
And his flesh it was eaten by the birds of the air.

I think that's pretty close to the Mr. Fox version of the song. I haven't listened to or sung it in awhile. The tune is in the lydian mode, I believe. Hope it helps.
