"The impact of the Beatles upon popular music cannot be overstated; they revolutionized the music industry and touched the lives of all who heard them in deep and fundamental ways. Landing on these shores on February 7, 1964, they literally stood the world of pop culture on its head, setting the musical agenda for the remainder of the decade. The Beatles' buoyant melodies, playful personalities and mop-topped charisma were just the tonic needed by a nation left reeling by the senseless assassination of its young president, John F. Kennedy, barely two months earlier. Even adults typically given to scorning rock and roll as worthless "kid's stuff" were forced to concede that there was substance in their music and quick-witted cleverness in their repartee. Without exaggeration, they transfixed and transformed the world as we knew it, ushering in a demographic shift in which youth culture assertively took over from its stodgy Eisenhower-era forbears. "
