Thread Name: Lyr Request: The Ratten Murders
Subject: Lyr Request: The Ratten Murders

Has anyone heard of this song? Here's what I can remember:

The first was mammy Ratten
She tried not to let him in
He [forgotten lyrics]
That's how the crime begin
That's how the crime begin

The next was granny Ratten
A settin' a 'fore the fire
He snuck on up behind her
And choked her with a wire
And choked her with a wire

The last was baby Ratten
All in his trundel bed
He stuck him in the short ribs
Until that child were dead
And he spat tabacie juice down on that golden head

Much appreciated for any help in solving my memory gap!
