I like Les Barkers version...
Myrtle Turtle
I have bought a small apartment in a lonely part of town
There are 27 stories, it's a long way from the ground

There I live with my friend Myrtle my companion my best friend
She ain't human she's a turtle and I love her till the end

Well she was standing by my window on a cold and cloudy day
When some wild and wilful wind blew my poor Myrtle clean away
Will the turtle be unbroken By and By Lord By and By
Lord help Myrtle as she hurtles through the sky Lord through the sky

I ran downstairs, I was crying, I must find her I must know
My poor Myrtle would be lying several hundred feet below
Will the turtle be unbroken By and By Lord By and By
Lord help Myrtle as she hurtles through the sky Lord through the sky

Was she sundered into sections as her shell fell to the ground?
Would I find 200 plectrums? My poor Myrtle all around?
Will the turtle be unbroken By and By Lord By and By
Lord help Myrtle as she hurtles through the sky Lord through the sky
LEAD BREAK
Oh caretaker, Oh caretaker, why do you lie there stone cold dead?
Poor man went to meet his Maker, something landed on his head.
And the turtle was unbroken By and By Lord By and By
For you guided my friend Myrtle through the sky Lord through the sky

Undertaker Oh undertaker, lay that poor man in his grave
Good Lord took that undertaker but my best friend she was saved.
Yes the turtle was unbroken By and By Lord By and By
For you guided my friend Myrtle through the sky Lord through the sky x2
