"(You're So Square) Baby I Don't Care" is a song written in 1957 by Jerry Leiber and Mike Stoller for the movie "Jailhouse Rock", starring Elvis Presley. Presley's version, the only song in which he plays the electric bass, was recorded on May 3, with the vocal track added on May 9, 1957 and released on his Jailhouse Rock EP. It reached number fourteen on the R&B charts. It later become a minor pop standard, with notable versions being performed by Buddy Holly, who included the song on his self-titled second album, and his version made the British singles chart in 1961.
The song's narrator addresses the object of their affection, and points out all the ways that the addressee is square, how they're out of touch with modern trends in music and romance. Then the narrator tells the subject of the song that they love them in spite of, and maybe because of this.
