Here's the poem read at the wedding.
THE BENEDICTION.With love and best wishes to Oliver and Malgorzata.
Blest pair of swans, O may you interbring
Daily new joys, and never sing ;
Live, till all grounds of wishes fail,
Till honour, yea, till wisdom grow so stale,
That new great heights to try,
It must serve your ambition, to die ;
Raise heirs, and may here, to the world's end, live
Heirs from this king, to take thanks, you, to give.
Nature and grace do all, and nothing art ;
May never age or error overthwart
With any west these radiant eyes, with any north
