Though their rankings may have changed, Novak Djokovic, Roger Federer, Andy Murray and Rafael Nadal will always be the Big Four in our hearts. And, apparently, in Judy Murray’s. She tweeted a photo of the group as members of the Beatles (it's unclear who made the artwork).

It may or may not be a coincidence that her son Andy (the new world No. 1) is depicted as quick-witted superstar John Lennon. Federer is in front as the gifted Paul McCartney, while Nadal is cast as the charismatic Ringo Starr and Djokovic as the introspective George Harrison.

And though opinions may differ on the choices, everyone is reminded that the quality of tennis’ Big Four was and is the stuff of legends.
