Speculation is running wild about a collaboration between the two sons of John Lennon and Paul McCartney after they posted a selfie to Instagram this week.

At the time, it was one of the most expensive ever created.

It was more than enough to prompt years of comeback rumors.

They recorded almost all of it during a marathon session that didn't even last 12 hours.

It’s just as historic and important as any of their other albums.

This single, written just a few days prior to the session, found John Lennon and Paul McCartney moving forward.

This controversy sparked death threats, becoming one of the reasons why they decided to stop touring.

It was only two days after their first appearance on 'The Ed Sullivan Show.'
