First dance flutter
James Blunt's 'You're Beautiful' is the 5-1 favourite to be Will and Kate's first dance song.
William Hill make 'Dont Wanna Miss A Thing' by Aerosmith the second favourite at 7-1 with 'Angels' by Robbie Williams and Shania Twain's 'You're Still The One' both at 8-1.
Other options are:
Everything I Do (Bryan Adams) 8-1
Chasing Cars (Snow Patrol) 10-1
Truly Madly Deeply (Savage Garden) 10-1
I Will Always Love You (Whitney Houston) 12-1
How Deep Is Your Love (Take That) 25-1
Unchained Melody (Righteous Brothers) 33-1
Sex On Fire (Kings On Leon) 50-1
You can also have a flutter on a whole host of Royal wedding proceedings - including upon where Prince William will kiss Kate on the balcony, the lips (1-5), the cheek (5-1) or the hand (16-1).
The fun doesn't stop there, with bets available on what meat will be served as the main course, what exact time Kate will arrive at the Abbey and even Kate to leave Will at the alter at 100-1!
