Witty Things To Say In A Wedding Card Alternative Love Song Quote For Wedding Invitations?

Alternative love song quote for wedding invitations? - witty things to say in a wedding card

I am getting married soon and I am working on our invitations. It's a casual affair, and I am looking for a love song as an alternative to the invitations. This is one of those things I wish I had a few lines that struck a note with a message before, because now I draw a blank written! Some special way, spiritually, in that direction. Any help?
