Code Poem For The French Resistance--Leo Marks

The life that I have
Is all that I have,
And the life that I have is yours.
The love that I have
Of the life that I have,
Is yours and yours and yours.
A sleep I shall have,
A rest I shall have,
Yet death will be but a pause.
For the peace of my years
In the long green grass,
Will be yours and yours and yours.

This is really more appropriate for a funeral than a wedding, I copied and pasted it from an undertakers web-site which we have saved on the enquiry desk favourites as it's the sort of thing we are asked for fairly regularly.
