John Lennon's son Sean and Paul McCartney's son James are clearly great friends – since they got together on Tuesday for a jamming session! Sean even took to Instagram to share the moment with a selfie of the pair, and fans couldn't believe their resemblance to their legendary dads. "You two definitely look like your famous fathers. I am still saddened by the loss of your father Sean. The world lost a wonderful person," one fan commented. "Wow. Great pic but it's kind of spooky. It's just like a young Paul and John," another said.

James is known to be very private about his music-icon dad, and in the past has refused to answer questions about their family life. During a BBC Three Counties Radio interview about his music in 2016, he was asked if he had felt pressure to follow in Paul's footsteps. "I wouldn't want to speak about my father you know? Like I’m not asking you about your father. It seems strange," he said at the time.
