Step 1 : Introduction to the question "Born on this day in 1963 to a mom named Cynthia, who was the first child to have a Beatle for a dad?"
...Julian Lennon was born to John and his first wife Cynthia, on this day in 1963, just as the Beatles were hitting the big time. As a young boy, Julian inspired three Beatles tunes: ‘Lucy in the Sky with Diamonds’ and ‘Good Night’ (written by his dad) and ‘Hey Jude’ (written by Paul to console Julian during his parents’ divorce). After John left Julian’s mom for Yoko Ono, the father and son were estranged for a period of time, but reconnected in the early 1970s. Julian followed in his father’s footsteps, becoming a pop star with 1984’s platinum-selling “Valotte” album.
