let the music play.......

The Beatles were an English rock group from Liverpool whose members were John Lennon, Paul McCartney, George Harrison, and Ringo Starr. They are one of the most commercially successful and critically acclaimed bands in the history of popular music.

In the United Kingdom, The Beatles released more than 40 different singles, albums, and EPs that reached number one. This commercial success was repeated in many other countries: their record company, EMI, estimated that by 1985 they had sold over one billion discs and tapes worldwide. The Beatles are the best-selling musical act of all time in the United States, according to the Recording Industry Association of America.

In 2004, Rolling Stone magazine ranked The Beatles #1 on its list of 100 Greatest Artists of All Time.According to that same magazine, their innovative music and cultural impact helped define the 1960s, and their influence on pop culture is still evident today.

The Beatles led the mid-1960s musical "British Invasion" into the United States. Although their initial musical style was rooted in 1950s rock and roll and homegrown skiffle, the group explored genres ranging from Tin Pan Alley to psychedelic rock. Their clothes, styles, and statements made them trend-setters, while their growing social awareness saw their influence extend into the social and cultural revolutions of the 1960s.

In March 1957, while attending Quarry Bank Grammar School in Liverpool, John Lennon formed a skiffle group called The Quarrymen.Lennon and the Quarrymen met guitarist Paul McCartney at the Woolton Garden Fête held at St. Peter's Church on 6 July 1957 and added him to the group a few days later.On 6 February 1958, the young guitarist George Harrison was invited to watch the group (who played under a variety of names) at Wilson Hall, Garston, Liverpool.McCartney had become acquainted with Harrison on the morning school bus ride to the Liverpool Institute, as they both lived in Speke. At McCartney's insistence, Harrison joined the Quarrymen as lead guitarist after a rehearsal in March 1958, overcoming Lennon's initial reluctance because of Harrison's young age. Members continually joined and left the lineup during that period, and in January 1960 Lennon's art school friend Stuart Sutcliffe joined on bass.Lennon and McCartney both played rhythm guitar and the group had a high turnover of drummers.
