Paul McCartney and John Lennon reunited through sons

The photo was posted to Sean Lennon’s Instagram page, where he can be seen posing alongside James McCartney with the simple caption: “Peekaboo…” The photo went viral instantly with Beatles fans commenting on the photo and questioning the motive behind the photo share.

At this time it is not known whether the sons of the famous Beatles have plans to collaborate.

Beatles 2.0 could be on the way

Since Beatles band members John Lennon, Paul McCartney, Ringo Starr, and George Harrison all have sons that happen to be involved in the music industry, there has always been talk of a possible Beatles 2.0 among fans. Sadly, if such a collaboration were to ever take place, only Paul McCartney and Ringo Starr would be alive to see it, as they are the only remaining original members still among the living.

John Lennon, as fans are all aware, was tragically killed on December 8, 1980 after being gunned down by killer Mark David Chapman in New York City. George Harrison is also no longer with us, as he died in November of 2001 from complications relating to lung cancer.

While nothing has officially been announced pertaining to such a project, it is more than clear based on Beatles fans' reactions to the viral selfie of Sean Lennon and James McCartney that most would not be opposed to the idea.

In an era where remakes, reboots, and revivals appear to rule in the entertainment world, many find themselves asking: Why not reboot the Beatles? After all, entertainment fans these days go wild over nostalgia in any form. What do you think of a possible Beatles 2.0 featuring the sons of original Beatles members? Would you want to go see them live and/or listen to a collaboration? As stated above, while there has not been any conformation of a collaboration, the selfie alone is enough to get fans talking about the possibilities.
