It wasn't until May 1965 that the album "Help!" was recorded in London, England, and McCartney seriously matched the melody with lyrics. After the first lyrics "yesterday" came out, he came up with the second sentence "all my troubles seemed so far away" for the rhyme; he also needed another three-syllable word, so there was "suddenly".

Producer George Martin proposed adding strings to the arrangement, but McCartney refused because "we are a rock band". Later, George Martin suggested to record the string version first, if you don't like it, you can discard it. So McCartney adopted George Martin's suggestion and performed the accompaniment with a string quartet.

"Yesterday" is an iconic single in the history of rock music. The string quartet in the song has changed the connotation of rock music. The beautiful melody of the song and the timeless lyrics portray the shadow that is lost in the torrent of time in the heart of the audience.
