Writing a melody as timeless and moving as The Beatles’ “Yesterday” isn’t something most of us would consider a “problem.” But in the mid-1960s, that’s precisely what that song was for the Fab Four.
Although the song is credited to the Lennon-McCartney partnership and billed as The Beatles (as was “the creed of the day,” per producer George Martin in Anthology), “Yesterday” was solely a Paul McCartney composition. The melody came to him in a dream, he came up with the lyrics, and he’s the only Beatle performing on the album version.
Therein was the problem: The Beatles were a rock band. And “Yesterday” didn’t have rock ‘n’ roll or a band to speak of. Speaking to PBS, Martin recalled the song “presented a problem for me, and I think for The Beatles, too, in that it didn’t fit the pattern. It wasn’t a song you could do with two guitars, bass guitar, and drums. It was something much more delicate.”
So, Martin set out to do the most important producer job of all: getting the roadblock out of the way. George Martin Helped Define “Yesterday,” and Paul Made Sure Some Rock Remained.
Both the band and producer George Martin recounted reaching a consensus that “Yesterday” ought to be performed solely by Paul McCartney. There was nothing that George Harrison, John Lennon, and Ringo Starr could think to contribute, and they preferred to sit out instead of muddying the song’s potential. It was Martin who suggested they bring in strings, though McCartney had his hesitations.
