Even if the word "pop" disappears from the English vocabulary, the influence of pop will remain. Pop has become part of British—and American—history. There has always been a close cultural link, or tie, between Britain and English-speaking America, not only in literature but also in the popular arts, especially music. Before the Second World War the Americans exported jazz and the blues. During the 1950s they exported rock and roll, and star singers like Elvis Presley were idolized by young Britons and Americans alike. The people responsible for the pop revolution were four Liverpool boys who joined together in a group and called themselves the Beatles. They played in small clubs in the back streets of the city. Unlike the famous solo stars who had their songs written for them, the Beatles wrote their own words and music. They had a close personal relationship with their audience, and they expected them to join in and dance to the "beat" of the music.
