Last but not least on our list is another Brit, John Lennon, seen here with son Sean. (Sean's rocking an old-school personalized t-shirt, we like your style, kiddo!) Fun rock kid fact: The Beatles song 'Hey Jude' was originally written by Paul McCartney as 'Hey Jules,' for John's eldest son Julian. Young Julian also gave The Beatles their inspiration for "Lucy in the Sky with Diamonds" - he later said the song was based on a picture he'd drawn of his classmate Lucy, surrounded by stars. So if you're ever feeling creatively challenged, try hanging out with your kids! They're the coolest, craziest, smartest and most entertaining people you will ever meet.
