An Old Estranged Fianc Of Mine Called Paul - Tumblr Posts
The relevance of "I saw her standing there" between John and Paul
Paul considers "I saw her standing there" one of the best song he has ever written in his book "the lyrics" from 2021.
I think John thought the same? Because he sung this with Elton in 1974 telling the world it is a song from "his estranged fiance Paul". John thought it would be funny to sing it and wondered how Paul would react about it in 1974.
Maybe the song has significance to the both of them? It's the first song on their first official album "Please, Please, Please" from 1963.

The first draft from Paul was genderneutral? IT COULD BE ABOUT JOHN. "You're just seventeen." Which is when Paul met him in 1957.
You're just seventeen
You act like a queen
You.....are beyond compare
So how could I dance with another (feels like a love declaration that's meant to last forever)
When I see you standing there.
"You are beyond compare", remember Paul saying everyone else just faded into background at the Fete when The Quarrymen was performing? You act like a queen would fit John too.
Update: Added Toot and Snore Session from March 1974 his only known jamming session with Paul post The Beatles break up where John said "When I saw me standing there, and I said gee is that me?"
