These pictures were taken after the Beatles Christmas performance on December 26th 1963. John invited his long time best friend Pete Shotton and his wife Beth, to stay with him and Cynthia for week near Christmas. Pete wrote about it in his book.
“The day after Christmas, Beth and I arrived, as promised, in London. Upon climbing the six flights of stairs to John’s new Kensington flat, we were greeted by Cynthia Lennon, her mum and baby Julian - whom I had never before seen. John, however, had already joined The Beatles at Finsbury Park’s Astoria Theater. “He’s been ringing up every ten minutes to see if you’ve arrived,” said Cyn. A moment later, the phone rang; sure enough, it was John. “Pete! Terrific! You made it!” he burbled. “Did you meet Julian? Isn’t he lovely?” - “He is beautiful, John, but it’s strange to hear you say it!” Prior to Julian’s arrival, John had never (to put it mildly) been exactly enamored of babies.” -Pete Shotton (“In My Life”)
