Paul McCartney Called This Controversial Beatles Song a "Parody" of This Iconic Classic Rock Band

Out of all the songs The Beatles had released, “Back In The U.S.S.R.” was the Fab Four's most controversial song. However, the reason why the song was released in the first place was because they were inspired by an iconic classic rock band that they repeatedly faced comparisons to. “Back In the U.S.S.R.” was inspired by The Beach Boys, and parodied their hit song “California Girls.”
