The Beatles: 1958–1970
McCartney and his friend John Lennon were in a skiffle group called the Quarrymen. In March 1958, at McCartney's urging, Harrison auditioned for the Quarrymen at Rory Storm's Morgue Skiffle Club, playing Arthur "Guitar Boogie" Smith's "Guitar Boogie Shuffle", but Lennon felt that Harrison, having just turned 15, was too young to join the band. McCartney arranged a second meeting, on the upper deck of a Liverpool bus, during which Harrison impressed Lennon by performing the lead guitar part for the instrumental "Raunchy". He began socialising with the group, filling in on guitar as needed, and then became accepted as a member. Although his father wanted him to continue his education, Harrison left school at 16 and worked for several months as an apprentice electrician at Blacklers, a local department store. During the group's first tour of Scotland, in 1960, Harrison used the pseudonym "Carl Harrison", in reference to Carl Perkins.
In 1960, promoter Allan Williams arranged for the band, now calling themselves the Beatles, to play at the Indra and Kaiserkeller clubs in Hamburg, both owned by Bruno Koschmider. Their first residency in Hamburg ended prematurely when Harrison was deported for being too young to work in nightclubs. When Brian Epstein became their manager in December 1961, he polished up their image and later secured them a recording contract with EMI. The group's first single, "Love Me Do", peaked at number 17 on the Record Retailer chart, and by the time their debut album, Please Please Me, was released in early 1963, Beatlemania had arrived. Often serious and focused while on stage with the band, Harrison was known as the "Quiet Beatle". That moniker arose when the Beatles arrived in the United States in early 1964, and Harrison was ill with a case of strep throat and a fever and was medically advised to limit speaking as much as possible until he performed on The Ed Sullivan Show as scheduled. As such, the press noticed Harrison's apparent laconic nature in public appearances on that tour and the subsequent nickname stuck, much to Harrison's amusement. He had two lead vocal credits on the LP, including the Lennon–McCartney song "Do You Want to Know a Secret?", and three on their second album, With the Beatles (1963). The latter included "Don't Bother Me", Harrison's first solo writing credit.
Harrison served as the Beatles' scout for new American releases, being especially knowledgeable about soul music. By 1965's Rubber Soul, he had begun to lead the other Beatles into folk rock through his interest in the Byrds and Bob Dylan, and towards Indian classical music through his use of the sitar on "Norwegian Wood (This Bird Has Flown)". He later called Rubber Soul his favourite Beatles album. Revolver (1966) included three of his compositions: "Taxman", selected as the album's opening track, "Love You To" and "I Want to Tell You". His drone-like tambura part on Lennon's "Tomorrow Never Knows" exemplified the band's ongoing exploration of non-Western instruments, while the sitar- and tabla-based "Love You To" represented the Beatles' first genuine foray into Indian music. According to the ethnomusicologist David Reck, the latter song set a precedent in popular music as an example of Asian culture being represented by Westerners respectfully and without parody. Author Nicholas Schaffner wrote in 1978 that following Harrison's increased association with the sitar after "Norwegian Wood", he became known as "the maharaja of raga-rock". Harrison continued to develop his interest in non-Western instrumentation, playing swarmandal on "Strawberry Fields Forever".
By late 1966, Harrison's interests had moved away from the Beatles. This was reflected in his choice of Eastern gurus and religious leaders for inclusion on the album cover for Sgt. Pepper's Lonely Hearts Club Band in 1967. His sole composition on the album was the Indian-inspired "Within You Without You", to which no other Beatle contributed. He played sitar and tambura on the track, backed by musicians from the London Asian Music Circle on dilruba, swarmandal and tabla. He later commented on the Sgt. Pepper album: "It was a millstone and a milestone in the music industry ... There's about half the songs I like and the other half I can't stand."
In January 1968, he recorded the basic track for his song "The Inner Light" at EMI's studio in Bombay, using a group of local musicians playing traditional Indian instruments. Released as the B-side to McCartney's "Lady Madonna", it was the first Harrison composition to appear on a Beatles single. Derived from a quotation from the Tao Te Ching, the song's lyric reflected Harrison's deepening interest in Hinduism and meditation. During the recording of The Beatles that same year, tensions within the group ran high, and drummer Ringo Starr quit briefly. Harrison's four songwriting contributions to the double album included "While My Guitar Gently Weeps", which featured Eric Clapton on lead guitar, and the horn-driven "Savoy Truffle".
Dylan and the Band were a major musical influence on Harrison at the end of his career with the Beatles. While on a visit to Woodstock in late 1968, he established a friendship with Dylan and found himself drawn to the Band's sense of communal music-making and to the creative equality among the band members, which contrasted with Lennon and McCartney's domination of the Beatles' songwriting and creative direction. This coincided with a prolific period in his songwriting and a growing desire to assert his independence from the Beatles. Tensions among the group surfaced again in January 1969, at Twickenham Studios, during the filmed rehearsals that became the 1970 documentary Let It Be. Frustrated by the cold and sterile film studio, by Lennon's creative disengagement from the Beatles, and by what he perceived as a domineering attitude from McCartney, Harrison quit the group on 10 January. He returned 12 days later, after his bandmates had agreed to move the film project to their own Apple Studio and to abandon McCartney's plan for making a return to public performance.
Relations among the Beatles were more cordial, though still strained, when the band recorded their 1969 album Abbey Road. The LP included what Lavezzoli describes as "two classic contributions" from Harrison – "Here Comes the Sun" and "Something" – that saw him "finally achieve equal songwriting status" with Lennon and McCartney. During the album's recording, Harrison asserted more creative control than before, rejecting suggestions for changes to his music, particularly from McCartney. "Something" became his first A-side when issued on a double A-side single with "Come Together"; the song was number one in Canada, Australia, New Zealand and West Germany, and the combined sides topped the Billboard Hot 100 chart in the United States. In the 1970s Frank Sinatra recorded "Something" twice (1970 and 1979) and later dubbed it "the greatest love song of the past fifty years". Lennon considered it the best song on Abbey Road, and it became the Beatles' second most covered song after "Yesterday".
In May 1970, Harrison's song "For You Blue" was coupled on a US single with McCartney's "The Long and Winding Road" and became Harrison's second chart-topper when the sides were listed together at number one on the Hot 100. His increased productivity meant that by the time of their break-up he had amassed a stockpile of unreleased compositions. While Harrison grew as a songwriter, his compositional presence on Beatles albums remained limited to two or three songs, increasing his frustration, and significantly contributing to the band's break-up. Harrison's last recording session with the Beatles was on 4 January 1970, when he, McCartney and Starr recorded overdubs to the song "Let It Be" for the soundtrack album of the same name.
