Cool to know this trivia.
And for all us poo pooers who say it’s about LSD and not Julian’s schoolmate, I propose it’s about both. Julian gave his dad the idea of Lucy in the Sky with Diamonds and while dropping acid he expounded on the idea.
Makes since to me. In the late 60s I saw Lucy in the sky a few times myself.
I’m sure for a hippy who liked to trip on acid, it seemed just trippy enough to write a song about. However the actual “Lucy in the sky with diamonds” was taken from the picture.
I’m sure I’ve “danced” with Lucy ... but everyone knew her as Nancy.
