Elizabeth's vows to William Turner:
I met him as a little girl,
Today I am his favourite pearl.
He treats me like a royal queen,
Each day with him is a surreal dream.
To marry him I could only pray,
For my heart is his, and will forever stay.
William's vows to Elizabeth Swann:
The governor's daughter I fancy dearly,
For she's the only thing I want sincerely.
I care for her like I do no other.
The only woman I've loved since my mother.
Today is the day I'll make her mine,
And each day from now will brightly shine.
Elizabeth Turner she is to me,
And together we'll sail the wide-open seas.
