My wife and I's song was "When you wish upon a star" by Olivia Newton John. As for the song when you walk down the aisle keep in mind that if you get married in a church, most churches will require a religious song. We couldn't even use the traditional "Wedding March".
My wife did have a Disney instrumental CD playing while she was getting ready and the people where filing into the church. She walked down the isle to music from "Ever After" a movie about Cinderella with Drew Barrymore.
Though I did have Mickey Mouse on my tux vest and tie, we did not have a lot of Disney during the ceremony. The reception though we had lot. Dinner music was Disney, first dance was "If I Never Knew You" from the pocahantas soundtrack. My champgne glass had Mickey and my wifes had Minnie. It was really fun.
