Don't Hurt My Little Sister

"Don't Hurt My Little Sister" is a song by the American rock band the Beach Boys from their 1965 album The Beach Boys Today!. Written by Brian Wilson with additional lyrics by Mike Love, Wilson attributed the song's inspiration to Honeys singers Marilyn and Diane Rovell and their sister Barbara. It was produced on June 22, 1964, making it the earliest-recorded song on the album.

Cover versions of the song have been recorded by the Surfaris (in 1965) and Shonen Knife (in 1996). Wilson originally wrote the song for the Ronettes and submitted it to their producer, Phil Spector, for his approval. Spector accepted on the condition that the song be rewritten with different lyrics as "Things Are Changing (For the Better), a version recorded by the Blossoms.
