2. Aged sixteen, John Lennon formed a skiffle group called The Quarrymen in March 1957. Fifteen-year-old Paul McCartney joined as a guitarist after he and Lennon met that July. When McCartney in turn invited George Harrison to watch the group the following February, the fourteen-year-old joined as lead guitarist. By 1960, Lennon's school friends had left the group, he had begun studies at the Liverpool College of Art and the three guitarists were playing rock and roll whenever they could get a drummer. Lennon's fellow student Stu Sutcliffe joined on bass in January. Sutcliffe suggested changing the band name to "The Beetles" as a tribute to Buddy Holly and The Crickets, and they became "The Beatals" for the first few months of the year. In May 1960 they undertook a brief tour of Scotland, as backing group for pop singer Johnny Gentle. After trying other names including "Johnny and the Moondogs", "Long John and The Beetles" and "The Silver Beatles", the band finally became "The Beatles" in August. The lack of a permanent drummer posed a problem when the group's unofficial manager, Allan Williams, arranged a resident band booking for them in Hamburg, Germany. Before the end of August they auditioned and hired Pete Best.

3. Paul McCartney Sir James Paul McCartney, MBE (born 18 June 1942) is an English musician, singer-songwriter and composer. McCartney is the most commercially successful songwriter in the history of popular music, according to Guinness World Records. After leaving The Beatles, McCartney launched a successful solo career and formed the band Wings with his first wife, Linda Eastman, and singer-songwriter Denny Laine. BBC News Online readers named McCartney the "greatest composer of the millennium", and BBC News cites his Beatles song "Yesterday" as the most covered song in the history of recorded music and since its 1965 release, has been played more than 7,000,000 times on American television and radio. In 1969, McCartney married American photographer Linda Eastman, whom he described as the woman who gave him "the strength and courage to work again" after the break-up of The Beatles. They had four children—Linda's daughter Heather (who was adopted by Paul), Mary, Stella and James—and remained married until Linda's death from breast cancer in 1998. In 2002, McCartney married Heather Mills, they had a child, Beatrice, in 2003. They separated in May 2006 and were divorced in May 2008.

4. John Lennon John Winston Ono Lennon, MBE (9 October 1940 – 8 December 1980). As the group disintegrated towards the end of the decade, Lennon embarked on a solo career that produced the critically acclaimed albums John Lennon/Plastic Ono Band and Imagine, and iconic songs such as "Give Peace a Chance" and "Imagine". Lennon disengaged himself from the music business in 1975 to devote time to his family, but re-emerged in 1980 with a new album, Double Fantasy. He was murdered three weeks after its release. Lennon revealed a rebellious nature and acerbic wit in his music, his writing, his drawings, on film, and in interviews, and he became controversial through his political and peace activism. He moved to New York City in 1971, where his criticism of the Vietnam War resulted in a lengthy attempt by Richard Nixon's administration to deport him, while his songs were adopted as anthems by the anti-war movement. At around 10:50 pm on 8 December 1980, as Lennon and Ono returned to their New York apartment in The Dakota, Mark David Chapman shot Lennon in the back four times at the entrance to the building. Lennon was taken to the emergency room of nearby Roosevelt Hospital and was pronounced dead on arrival at 11:07 pm. Earlier that evening, Lennon had autographed a copy of Double Fantasy for Chapman.

5. George Harrison George Harrison, MBE (25 February 1943 – 29 November 2001) was an English rock musician, guitarist, singer-songwriter, actor and film producer. Harrison is listed at number 21 in Rolling Stone magazine's list of "100 Greatest Guitarists of All Time". In his work as a film producer, he collaborated with people as diverse as the members of Monty Python and Madonna. He was married twice, to model Pattie Boyd from 1966 to 1974, and for 23 years to record company secretary Olivia Trinidad Arias, with whom he had one son, Dhani Harrison. He was a close friend of Eric Clapton. He is the only Beatle to have published an autobiography, with I Me Mine in 1980. Harrison died of lung cancer in 2001.

6. Ringo Starr Richard Starkey, MBE (born 7 July 1940) better known by his stage name Ringo Starr, is an English musician, singer-songwriter, and actor. He became The Beatles' drummer in August 1962, taking the place of Pete Best. Starr generally sang at least one song on each studio album as part of an attempt to establish the vocal personality of all four members. In some cases, Lennon or McCartney wrote the lyrics and melody especially for him, as they did for "Yellow Submarine" from Revolver and "With a Little Help from My Friends" on Sgt. Pepper's Lonely Hearts Club Band. After the announcement of the break-up of The Beatles on 10 April 1970, Starr released two albums before the end of that year. Aside from The Beatles' films A Hard Day's Night (1964), Help! (1965), Magical Mystery Tour (1967), Yellow Submarine (1968), Let It Be (1970), Starr has acted in several films such as Candy (1968), The Magic Christian (1969) (alongside Peter Sellers), Blindman (1971), Son of Dracula (1974) and Caveman (1981).

Broadcast Music Incorporated (BMI) asserts that it was performed over seven million times in the 20th century alone.
