Here are the lyrics I remember the Kingston Trio usin'.

TOM DOOLEY

CHORUS: 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 and there I took her life
I met her on the mountain & stabbed her with my knife (CHO)

Hand me down my banjo, I'll pick it on my knee
This time tomorrow, it'll be no good to me (CHO)

This time tomorrow, reckon where I'd be
If it hadn'-a been for Grayson, I'd be in Tennessee (CHO)

This time tomorrow, reckon where I'd be
In some lonesome valley, hangin' on a white oak tree

These are also the lyrics printed in "Rise Up Singing".
