Fifteen real couples share their first-dance stories.

The couple: Julie and Jon

The song: "Spot in the Corner" by Steve Carlson

Who played it: Steve Carlson

"Steve Carlson, one of Jon's groomsmen and best friends, is a musician," says Julie, "and he wrote a song called 'Spot in the Corner' that we love. So we asked him to sing it for our first dance. But before we started, Jon surprised me by picking up a guitar and singing a song he'd written for me called 'I Prayed.' Afterwards he came up to me and we started dancing—I'll remember the moment forever."
