James Blunt
Two choirs, one orchestra, a fanfare team and trumpeters will play at the wedding, but what tune William and Kate will dance to for the first time as a married couple remains unknown.
At 5-1, the bookmakers' favorite is James Blunt's "You're Beautiful," followed by "Everything I Do" by Bryan Adams and Shania Twain's "You're Still the One" (both 8-1). While there's a royal reference in their name, Kings of Leon's "Sex on Fire" is the long shot at 50 to 1.
