"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 other three 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 2002 McCartney asked Yoko Ono if she would allow reversing the credit on the song to read "McCartney/Lennon". Ono refused.
"Yesterday" was voted the best song of the 20th century in a 1999 BBC Radio 2 poll of music experts and listeners. In 2000, "Yesterday" was voted the #1 Pop song of all time by MTV and Rolling Stone Magazine. In 1997, the song was inducted into the Grammy Hall of Fame.
