Mal Evans - a man behind the Beatles

I never heard of him, but I wondered if he was parodied in The Rutles and I just didn’t know who the character was supposed to be.

So I googled “Mel Evans in the Rutles” (spelled incorrectly) and Google AI tells me:

Yes, Mal Evans The Beatles’ trusted road manager and friend, was parodied in The Rutles: All You Need Is Cash as the character Percy “Thames” Thistlewaite a large, loyal, but somewhat bumbling aide, played by Neil Innes, capturing Evans’s role as the Beatles’ protective, ever-present “big guy” in a humorous, exaggerated way

OK, I have seen the Rutles like 30 times and never saw a character by that name, or that even sounds like that. Then I corrected the spelling to Mal and google AI informed me helpfully:

While the primary members of The Beatles are parodied in The Rutles through the main characters (Ron Nasty, Dirk McQuickly, Stig O’Hara, and Barry Wom), Mal Evans himself is not explicitly parodied as a specific recurring character in the film

AI is going to be the salvation of the world. Snort.

FWIW, IMDB lists no such character played by Innes or anyone else. So where did that crap come from?
