Sporting crisp white shirts, the future king and his soon-to-be missus appear relaxed and in love, if not matchy-matchy.
"We are both so delighted that you are able to join us in celebrating what we hope will be one of the happiest days of our lives," write "William" and "Catherine" in the program. "The affection shown to us by so many people during our engagement has been incredibly moving, and has touched us both deeply. We would like to take this opportunity to thank everyone most sincerely for their kindness."
Other revelations inside the 28-page document:
-- Middleton will walk down the aisle to the tune "I Was Glad" by Sir Charles Hubert Hastings Parry, written for the coronation of King Edward VII at Westminster Abbey in 1902.
-- The bride will not promise to "obey" her husband. Rather, she'll vow to "love, comfort, honor and keep" the prince.
-- William won't wear a wedding ring, which some people find bizarre, so only he will say "With this ring I thee wed" while slipping the band on the bride's finger.
