... was the day John's first son, John Charles Julian Lennon, was born. In honor of Julian's 47th birthday today, below is "Hey Jude," which Paul wrote in 1968 to help the young boy cope with his parents' divorce. Without question, it's a classic.
Let me add that one of my favorite small moments in The Beatles' body of work comes at the 2:41 mark of this song, when John or George (or perhaps both) does a spot harmony on the line, "Don't make it bad." I've always really enjoyed how the vocal just eases in next to Paul's. It's subtle and affecting.
