Which girl group recorded “Mr. Sandman,” a 1954 US number-one hit?

The Chordettes recorded “Mr. Sandman,” a 1954 US number-one hit.

The Chordettes were an American female vocal quartet known for close harmony and a polished pop sound. Their recording of “Mr. Sandman,” written by Pat Ballard, became one of the best-known examples of mid-1950s vocal-group pop.

The song reached number one on the Billboard charts in 1954 and used layered vocals, distinctive rhythmic phrasing and a memorable request to the mythical Sandman. Its arrangement helped make the recording instantly recognizable beyond the group’s original audience.

The song is sometimes confused with later versions by artists such as Chet Atkins or the Andrews Sisters. Those recordings do not change the identity of the group behind the famous 1954 hit. The Chordettes’ version is the classic girl-group vocal recording most commonly associated with the song.
