Watch a timeline of The Beatles morphing from photo to photo as they age from 1960 to 2017. In 1960, George was 17, Paul was 18, and John was 20. Ringo was also 20, but he didn't join the Beatles until 1962, which means Paul McCartney is the only one that appears in all 57 years. There was no year without music to accompany each shift, from either The Beatles or at least one of them as a solo act.
Angel Nene put this together from publicity photos, concert footage, album covers, interviews, documentaries, and one rather obvious cartoon. There's a list of the songs used at the YouTube page. -via Boing Boing
