you didn't think it was AI narration.
Although the narration still sounds like AI to me, and did to at least one person commenting on YouTube about most of his videos whose comments I checked, he denied a specific question about it at one point.

Not to be rude, but is this an AI narration?

not rude Tommy. As someone who suffers from severe AI anxiety, I can assure it is very much my real voice (with all the awkward breaths cut out haha)
His mispronunciation of Mersey, which seemed really odd for a dedicated Beatles fan, was explained or blamed on his being American. That doesn't explain other mispronunciations, or some clueless (but typical of AI) choices to help illustrate the videos - or saying Ringo's real name is Richard Starkley in one video - but freelancing amateurs can make mistakes that won't be caught by editors.
I also checked for any Reddit discussions of that YouTube channel, saw some recommendations of it by Beatles fans, and no objections there to it, let alone any suggesting it's AI.
I'm still not entirely certain he didn't use AI. But I'm not positive he did.
I won't watch the videos myself because it bothers me that he's asking people to send him money via Patreon, and he's monetizing his YouTube channel with sponsorship, while giving zero credit to all the sources he took information and video clips and photos from. Especially since it's quite possible he had AI research for him and write all or most of the scripts. He apparently has no credentials as a writer. But since the 43 videos on his channel are spaced out over a year and a half, I suppose it's also possible he wrote the scripts himself. More possible, anyway, than when the AI-generated channels are releasing new videos with long scripts every day or two.
