1961: What an extraordinary photograph...

By Mike McCartney, so I say... 

Quoting:

"call our kid “Rambo Paul” in this photo, because his look reminds me of Stallone. I think Pete was doing one of the silly voices from The Goon Show. Then there’s nipple-shooting George. I have no idea why he’s pointing at Paul’s nipple. And we can’t ask him now.

The most important thing this photograph communicates is joy. It’s all about the fun, the camaraderie. They were totally relaxed in each other’s company and bounced off each other. All this business about the Beatles’ arguments – we all have arguments, for Christ’s sake. This photograph is a much stronger reflection of the reality."
