"Yesterday" is a song originally recorded by The Beatles for their 1965 album Help!. The song remains popular today with more than 2,200 cover versions, and is one of the most covered songs in the history of recorded music. At the time of its first appearance the song was released by The Beatles' record company as a single in the United States but not in the United Kingdom (for further details see below). Consequently, whilst it topped the American chart in 1965 the song first hit the British top 10 three months after the release of Help! in a cover version by Matt Monro. "Yesterday" was voted the best song of the 20th century in a 1999 BBC Radio 2 poll of music experts and listeners and was also voted the No. 1 Pop song of all time by MTV and Rolling Stone magazine the following year. In 1997, the song was inducted into the Grammy Hall of Fame. Broadcast Music Incorporated (BMI) asserts that it was performed over seven million times in the 20th century alone.

"Yesterday" is a melancholy acoustic guitar ballad about a break-up. It was the first official recording by The Beatles that relied upon a performance by a single member of the band, Paul McCartney. He was accompanied by a string quartet. The final recording was so different from other works by The Beatles that the band members vetoed the release of the song as a single in the United Kingdom. (However, it was issued as a single there in 1976.) Although credited to "Lennon–McCartney", the song was written solely by McCartney. In 2000 McCartney asked Yoko Ono if she would agree to change the credit on the song to read "McCartney–Lennon" in the The Beatles Anthology but she refused.
