"Bad Boy" is a song composed and recorded by Larry Williams. The song was recorded at Radio Recorders in Hollywood, California on August 14, 1958. The musicians on the recording included Williams on vocals and piano, Earl Palmer on drums, René Hall on guitar, Jewell Grant on baritone sax, Plas Johnson on tenor sax, and Ted Brinson on bass. The record did not break the Top 40 charts in the United States.

"She Said Yeah" was originally the B-side of the Larry Williams single, and has been covered by the Rolling Stones and the Animals, among others. "She Said Yeah" was written by rockabilly singer Roddy Jackson and Sonny Bono (under the name Don Christy). The Beatles loved the song and almost certainly performed it on stage and fully intended to record it. Paul McCartney in the liner notes to his album Run Devil Run said "Me and John [Lennon] particularly loved Larry Williams...Bony Moronie...John did Slow Down...I was always going to do She Said Yeah". Roy Young (who was invited to join The Beatles) recorded a cover version in 1959. Paul McCartney finally recorded it in 1999.

The song, recorded between 1957 and 1958, also appears on the 1992 compilation of the same name.
