Have you noticed how even saying the names of The Beatles flows so smoothly ? - “John, Paul, George and Ringo”. - It’s so easy to remember and say. - Almost musical.
Contrasted to The Rolling Stones, for example. - “Mick, Keith, Bill, Charlie and Ronnie.” - Or U2, “Bono, The Edge, Adam and Larry”. - Saying their names is hard to remember and clunky.
And “John, Paul, George and Ringo” has a “homely” feel to it, like they’re ones family, neighbours or close friends.
Moreover, “John, Paul, George and Ringo” sounds like some sort of magical spell, an incarnation, like “Abracadabra”.
Maybe just saying their names is a magical spell and causing some sort of energy transference.
