I love Madonna's Crazy for You, and I think it would make a great 'first dance' song. I don't think it would be quite appropriate in a church wedding, but for the reception it would be perfect.
I'm not married, so you can't see any pictures of my wedding day, but I found this fabulous picture of a bride in the Kremlin gardens. There are so many things to prompt me to write in this picture. Wonderful as the bride's hat is, it's the two ladies in black who intrigue me most - the one looks confused and I have no idea why the other is looking at her dress like that. Imagination, it's time to fill in the gaps!
