The Beatles arrive at John F. Kennedy International Airport in New York on February 7, 1964. Public domain via Wikimedia CommonsOn December 26, 1963, syndicated Hollywood columnist Erskine Johnson issued a stark notice in newspapers across the United States.Warning: Beatles Are Coming, the headline read, like a 20th-century version of Paul Reveres midnight ride.Johnson, for one, was not impressed with the British band, who had just released their breakout singles, I Want to Hold Your Hand and I Saw Her Standing There, in the U.S. that day.I watch. Im appalled, he wrote after attending a Beatles show in London. He described the stage presence of John Lennon, Ringo Starr, George Harrison and Paul McCartney as eels after an explosion in a wig factory.Their music was brash, loud and full of guitars, and it apparently had little or no melody. Worse, Johnson found, were the fanatic fans who inspired the term Beatlemania. Girls fell to their knees during the concert and beat their fists against the floor, he reported.The thought of U.S. teenagers becoming Beatle Bewitched is frightening, Johnson wrote. It isnt fair. Yeah, yeah, yeah.The Beatles' first appearance on American TV -- NBC NewsWatch on But, indeed, the Beatles were coming stateside, having already conquered their home island. On December 26, they already held five top-20 slots on the British pop charts, including the coveted first two. (The Fab Four also made a cameo appearance in the 20th spot on Dora Bryans single All I Want for Christmas Is a Beatle, in which the singer pines for a real live Liverpool boy.)Four days before releasing their second studio album With the Beatles on November 22, the same day President John F. Kennedy was assassinated, the Beatles had made their first television appearance in the U.S. during a four-minute report by NBCs Edwin Newman. Millions of people watched, and hype for the British groups American visit skyrocketed.Whatever the nature of Beatlemania, this country is about to be exposed to its carriers, the New Yorker wrote in a profile of the Beatles manager Brian Epstein, who was tirelessly arranging the bands visit to America.On February 7, 1964, it finally happened: The Beatles touched down at the recently renamed John F. Kennedy Airport in New York. As they stepped off their airplane, they were met by a crowd of 200 jostling reporters and photographers and some 4,000 fans, mostly teenaged girls, who lined the rooftop observation deck of the airports International Arrivals Building in a great singing, shrilling mass, Jonathan Gould wrote in Cant Buy Me Love: The Beatles, Britain and America. The Beatles performing on "The Ed Sullivan Show" in February 1964 Public domain via Wikimedia CommonsAfter a chaotic and quippy press conference, four black Cadillac limousines brought each Beatle individually to the Plaza Hotel, where they were trapped by throngs of press and fans.Then, on February 9, the Beatles had their formal television introduction to the American public through a live performance on the Ed Sullivan Show. Seventy-three million Americans, roughly 34 percent of the population, tuned in, and Beatles fans in the studio were so rowdy while the shows other guests performed that Sullivan at one point joked, If you dont keep quiet, Im going to send for a barber.To joyous screams, the four Beatles came onto the stage. They ripped through three songs: All My Loving, Till There Was You and She Loves You. During the second number, the camera cut between individual Beatles, displaying their first names and introducing them personally to America. (Under Lennons name, text stated, SORRY GIRLS, HES MARRIED.) The show then went to commercial, but the course of rock music was forever changed.Writing for Smithsonian, Joseph Stromberg described the Beatles performance on the show as a watershed moment, a turning point in the history [of] American music that inextricably influenced a huge proportion of all the pop and rock thats come since.In retrospect, Johnsons warning back on December 26 was apt.
