Instead of aiming to be the first one to get it right, Richard is just trotting with the crowd. His problem, not mine.
I don't want to get between two good friends, but Richard clearly does know that his real name is Orenduff, but the only reason Orenduff is on WATN is because of the 1934 Indy 500, and apparently that incorrectly listed him as Ornduff. So Richard calls him Ornduff, and then makes the point that his name was actually Orenduff. Almost every other source simply calls him Ornduff.
If he changed to Orenduff, then all the people looking for Ornduff would be unable to find him, and Richard would get emails telling him he'd missed out Ornduff.
I really don't think he's doing anything wrong. All I could suggest is that instead of just saying "Real name Orenduff", Richard could explain that he's only called Ornduff here because Fox and other Indy 500 sources have mistakenly called him Ornduff over many decades.
