A dad of two strappin’ lads speaking here. My kids always fell asleep when I would sing ‘My Bonnie Lies Over The Ocean’. There’s a nice page with the lyrics and the melody at http://www.duchessathome.com/childrensongs/mybonnie.html
Another favourite (puts them straight to sleep) was Tom Dooley:
INTRO (spoken):
Throughout history, there’ve been many songs written about the eternal triangle. This next one tells the story of a Mr. Grayson, a beautiful woman, and a condemned man named Tom Dooley…
When the sun rises tomorrow, Tom Dooley… must hang…
Hang down your head, Tom Dooley,
Hang down your head and cry;
Hang down your head, Tom Dooley,
Poor boy, you’re bound to die.
I met her on the mountain,
There I took her life;
Met her on the mountain,
Stabbed her with my knife.
Hang down your head, Tom Dooley,
Hang down your head and cry;
Hang down your head, Tom Dooley,
Poor boy, you’re bound to die.
This time tomorrow,
Reckon where I’ll be;
Hadn’t a-been for Grayson,
I’d a-been in Tennessee.
Hang down your head, Tom Dooley,
Hang down your head and cry;
Hang down your head, Tom Dooley,
Poor boy, you’re bound to die.
Hang down your head, Tom Dooley,
Hang down your head and cry;
Hang down your head, Tom Dooley,
Poor boy, you’re bound to die.
This time tomorrow,
Reckon where I’ll be;
Down in some lonesome valley,
Hangin’ from a white oak tree.
Hang down your head, Tom Dooley,
Hang down your head and cry;
Hang down your head, Tom Dooley,
Poor boy, you’re bound to die.
Hang down your head, Tom Dooley,
Hang down your head and cry;
Hang down your head, Tom Dooley,
Poor boy, you’re bound to die.
Poor boy, you’re bound to die;
Poor boy you’re bound to die;
Poor boy, you’re bound to die…
