Hold still
Don’t move I say
Wilt thou hear
My elegy
Head high
Preserve my pride
I shall defy the gallows
I and you and me
Well we just don’t know
What love can do
I pledge to you
That I won’t deceive
The heart that’s mine
As here I sit
I vow
Your history does not
Perish my love
The shame
Will be mine for a
Scarlet woman thou art
I and you and me
Well we just don’t know
What love can do
I pledge to you
That I won’t deceive
The heart that’s mine
Dead from the grave
We’re all slaves
To what we’ve got
Love
Is been through
The door
