influences between the Beatles and one of their favorite new bands, the Byrds". The two groups formed a friendship in early August 1965, when the Byrds were enjoying international success with their debut single, a folk rock interpretation of Bob Dylan's "Mr. Tambourine Man", and Harrison and John Lennon attended their first shows in London. Although the concerts received unfavourable reviews in the British music press, Harrison lauded the band as "the American Beatles". In late August, the Byrds' Jim (later Roger) McGuinn and David Crosby met up with the Beatles in Los Angeles, where they discussed with Lennon and Harrison the music of Indian sitarist Ravi Shankar and American Indo-jazz pioneer John Coltrane. The meeting led to Harrison introducing the sitar on Lennon's song "Norwegian Wood", and to Crosby and McGuinn incorporating Indian influences into the Byrds' "Why" and "Eight Miles High". Harrison likened "If I Needed Someone" to "a million other songs" that are based on a guitarist's finger movements around the D major chord. The song is founded on a riff played on a Rickenbacker 360/12, which was the twelve-string electric guitar that McGuinn had adopted as the Byrds' signature instrument after seeing Harrison playing one in A Hard Day's Night. When McGuinn told him this in Los Angeles, Harrison was appreciative of the recognition, particularly as his contributions to the Beatles were often overshadowed by those of Lennon and Paul McCartney. In late 1965, Harrison acknowledged the Byrds' influence on "If I Needed Someone" when he sent a copy of the Beatles' new album, Rubber Soul, along with a message for McGuinn and Crosby, to Derek Taylor, the Byrds' publicist. In his note, Harrison said that the riff was based on the one McGuinn had played on the Byrds' adaptation of "The Bells of Rhymney", and that the rhythm was based on the drum part in "She Don't Care About Time". McGuinn later recalled: "George was very open about it. He sent [the record] to us in advance and said, 'This is for Jim' – because of that lick [in 'The Bells of Rhymney']." Writing in The Beatles Anthology, Harrison commented on the difficulties he faced as a nascent songwriter during the Rubber Soul period, relative to Lennon and McCartney, both of whom had been writing "since they were three years old". He said he wrote "If I Needed Someone" as a love song to Pattie
