text: Beatlemania in the United Kingdom The phenomenon known as Beatlemania originated in the United Kingdom, birthplace of the Beatles, when the band first realised enormous popularity there in 1963. Returning in 1962 from a highly formative two-year residency in Germany, the Beatles achieved a commercial breakthrough with their second UK single release, "Please Please Me" early in 1963, but gained "Superstar" status with the release of "She Loves You" later that year. There followed an almost non-stop series of concerts and tours, attended with feverish enthusiasm across the UK, for the whole of the following year. The Beatles' popularity in the UK came to exceed even that of the notable American artists Tommy Roe, Chris Montez and Roy Orbison, whose UK chart success at the time did not keep them from being overshadowed by the Beatles during their 1963 nationwide tours with the lower-billed band — an achievement previously unknown for a UK act.

text: The Beatles The Beatles were an English rock band formed in Liverpool in 1960. With members John Lennon, Paul McCartney, George Harrison and Ringo Starr, they became widely regarded as the foremost and most influential act of the rock era. Rooted in skiffle, beat and 1950s rock and roll, the Beatles later experimented with several musical styles, ranging from pop ballads and Indian music to psychedelia and hard rock, often incorporating classical elements and unconventional recording techniques in innovative ways. In 1963 their enormous popularity first emerged as "Beatlemania", and as the group's music grew in sophistication in subsequent years, led by primary songwriters Lennon and McCartney, they came to be perceived as an embodiment of the ideals shared by the counterculture of the 1960s.

text: Beatles and Rolling Stones rivalry "The Beatles" and "The Rolling Stones" were arguably the biggest bands of the 1960s. Both bands started their careers in the early 1960s in the United Kingdom and rose to fame as part of the British invasion. The Beatles rose to fame in the UK in 1963 with their singles "Please Please Me" and 'Love Me Do". After a successful album contract the band decided to leave Liverpool and move to London. The Rolling Stones were a struggling band at the time and the Beatles had become famous as a self contained Rock Band. Original song content was getting tougher to acquire in the United Kingdom so the Rolling Stones were a Rock and Roll Blues cover group. On meeting the Beatles at a London Pub; John Lennon and Paul McCartney agreed to write an original single for the Rolling Stones called "I Wanna Be Your Man". The song gave the Stones their first commercial success and Mick Jagger and Keith Richards began writing as well.
