Inspired by Roger McGuinn's guitar work for The Byrds, If I Needed Someone was written by George Harrison and first appeared in the UK on the Rubber Soul album.
If I Needed Someone is like a million other songs written around a D chord. If you move your finger about you get various little melodies. That guitar line, or variations on it, is found in many a song, and it amazes me that people still find new permutations of the same notes.
McGuinn was already aware of the similarity. It is, additionally, interesting that Harrison's own 12-string guitar work on 1964's A Hard Day's Night album had played a key role in the development of The Byrds' own Rickenbacker-led jangling sound.
The song also revealed Harrison's burgeoning interest in Indian music. The song is based largely around a single chord, which anticipated the droning styles of later songs such as It's All Too Much and Blue Jay Way.
If I Needed Someone was the only one of George Harrison's songs to have become a part of The Beatles' live repertoire. It is believed to have been performed at every Beatles concert in 1966, and was played at their final show at San Francisco's Candlestick Park on 29 August.
In the studio
The Beatles recorded If I Needed Someone over two sessions. In the first of these, on 16 October 1965, they recorded just the basic rhythm track, nailing it in a single take.
Two days later they completed the song with a number of overdubs. These included Harrison's lead vocals, harmonies from Lennon and McCartney, and tambourine by Starr.
