The royal couple - who will marry in London's Westminster Abbey tomorrow (29.04.11) - have said they have found the world's interest in their forthcoming nuptials "incredibly moving" in an official wedding program that was released today (28.04.11).
In the 28-page booklet - which reveals details of the wedding service including the vows and music - they state: "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.
"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."
The program reveals that the beautiful 29-year-old bride will walk down the aisle to choral anthem 'I Was Glad' by Sir Charles Hubert Hastings Parry, which was originally composed for the wedding of William's great-great-great grandfather Edward VII.
Other songs to be played are 'Jerusalem' by William Blake and traditional tune 'Greensleeves', which is believed to have been written by King Henry VIII.
Meanwhile, Kate will be following in the footsteps of William's mother, Princess Diana, by omitting the word "obey" from her vows.
Instead of promising a lifetime of obedience towards her future husband, she will opt to "love and comfort" her spouse in the same way the late Diana did when she married Prince Charles in 1981.
