Luke Gallows and Karl Anderson appeared on the Sam Roberts Wrestling Podcast, and they both talked about how Vince did not even know Luke was Festus from back in 2007-2008. 

Karl Anderson had said the following about it.

“The best part of the Festus character is that we heard from Talent Relations, or the Head of Talent Relations is that Vince doesn’t even remember that he was Festus.”

Karl also said this to Luke about what Mark Carano said to Luke.

“We go up to the Gorilla Position, and Mark Carano would say, I’m going to go tell Vince and remind him that you were Festus. I would say, don’t tell Vince, I need this run right now.”

Gallows also added onto this commentary about how the wife didn't even know about it as well.

“I don’t know if we’re even allowed to say the word, but my wife didn’t even know that I was Festus when I married her, which is real.”
