Quote: JEAN CAPDOUZE "You have a right to your opinion. I don't challenge that. But I have a right to mine. If Terence O'Connor were to be knighted, for example (say for services to rugby union), he would be knighted as Sir Terence, not Sir Terry. Sir Terry would be just silly. I believe in giving him the minimum respect he deserves.'"
Wrong as ever. There are very few occasions that you are required by law to use your legal name, a name you can in fact change any time you wish.
A knighthood in not one, the queen knights Elton John as sir Elton which is his stage name and one he chooses to use daily. I can find no evidence that he’s changed his name legally. I know for certain that Sir Michael Cain is still legally called Michael Mickle something because he says so in his autobiography.
So HRH would have no issue knighting Sir Terry.
