There is a motto which has been borne by many of my ancestors - a noble motto, "I serve". Those words were an inspiration to many bygone heirs to the Throne when they made their knightly dedication as they came to manhood. I cannot do quite as they did.

And I never forgot this as long as I've ever performed, no matter how crap I had felt before I went on stage. I just remember Tina Turner going up there, singing her heart out for everybody, and meantime she had a 102-degree fever and she was feeling terrible.

There is no greater power in heaven or on earth than the commitment to a dream.

I take this opportunity to mention the strength I draw from my own family. The Duke of Edinburgh has made an invaluable contribution to my life over these past fifty years, as he has to so many charities and organisations with which he has been involved.

I shall not have the strength to carry out this resolution alone, unless you join in it with me as I now invite you to do. I know that your support will be unfailingly given. God help me to make good my vow and God bless all of you, who are willing to share with it.

Through the inventions of science I can do what was not possible for any of them. I can make my solemn act of dedication with a whole Empire listening. I should like to make that dedication now. It is very simple.
