But even without the gift of hindsight, it was easy to tell something special was happening when the Beatles appeared on The Ed Sullivan Show, a remarkable occasion that happened 60 years ago this February. This moment was a perfect storm of all the right forces meeting at the right time and place.

Crowds they were relatively used to - but the setting on The Ed Sullivan Show was totally new to the Beatles. "When we first came here, we’d never seen this kind of thing," recalled McCartney in a 2009 interview with David Letterman.

Tom Parker wishing them a tremendous success in our country," Sullivan said to his eager audience. "Now tonight the whole country is waiting to hear England’s Beatles."

An episode of Everything Fab Four details how this feat was accomplished, with testimony from Margo Precht Speciale, granddaughter of Sullivan and daughter of producer Bob Precht. "There are two stories – the PR story and the real story," she explained.
