So we all know Baby’s In Black is a special song for John and Paul, they grin and dance and stare into one another’s eyes when playing it live. Which they did a lot.
Though I quite liked the theory that it was about Astrid and Stu, it was never perfectly satisfying, because I don’t think John ever thought of Astrid that way. I always preferred the idea that it was Paul talking about John and Stu.
Well!
Listen carefully to Paul’s harmony at 0:53 in this video. I’m pretty sure he’s saying “till he sees the mistakes he has made”
