I've heard it said that Paul wrote this song for Julian Lennon after the divorce of his parents and the arrival of Yoko into is dad's life. The original name was "Hey Jules". Its also said that John resented this song because he saw it as a veiled statement that Paul was ready to split the Band because of issues he had with John.
Here's a video of the song. I will admit, I love/loved John and for some reason, Paul has always bugged me. I know that's ridiculous, but its true. John and George were the ones I admired, Ringo is a likeable bloke, but Paul...I never saw what the big deal was (other than the brilliant collaborations he did with John). Like it or not, they were a good team.
I know women STILL scream about how "cute" Paul is with his puppy-dog eyes and charm, but give me a long-haired, bespectacled guy with an orange bow-tie any day :)
Does anyone know the true facts on "Hey Jude"?
