Ours were:

Pre ceremony: "This Corner of the Earth" by Jamiroquai
Me walking up the aisle: "Lovely Day" by Bill Withers. It was a remixed jazz version
Us entering the reception dinner: "Crazy Little Thing Called Love" by Queen
Waltz: "Someone Like You" which is a Van Morrison Track, but we had the Dina Carroll cover (from the Bridget Jones movie soundtrack.)
