In 1964, the United States was home to just under 192 million -- and on Monday, February 10th, 1964, 73 million of them were talking about seeing The Beatles the night before on The Ed Sullivan Show.
Among them were probably some criminals, because George Harrison said he was told that there was no crime reported for the 10 minutes they performed that Sunday night.
Paul McCartney put it best when he told us that for so many it became a moment that you will always remember where you were. "You know, it's like where were you when Kennedy was shot?" And their performance helped comfort Americans still mourning the death of President Kennedy, who'd been killed less than three months earlier.
