The single best song for a wedding i.m.o. is Garnet Roger's "All That Is"

Who can tell when in love you'll finally fall
Some live in vain and never love at all
But as lightning strikes or as a small insistant voice
If we are blessed we will hear and heed the call

Chorus
Give you love and never count the cost
Lose your heart and never call it lost
May your love be a shelter to the ending of your days
love is all that is and all that ever was

May your love grow strong and always kind
may your hearts grow forever more entwined
In the brightest day or in the stillness of the night
May it be each other's hand you seek and find

Never more to be alone
Ever close you have grown
Forever now may no distance come between
And in each other's loving hearts you find a home


It's off his album, Sparrows Wing... deffinatly worth the price of admission!
