"Sisters" is a popular song written by Irving Berlin in 1954, best known from the 1954 movie White Christmas.
Both parts were sung by Rosemary Clooney (who served as Vera-Ellen's singing vocal dub for this song, while Trudy Stevens dubbed Vera-Ellen's other songs in the film).
The movie White Christmas also starred Bing Crosby and Danny Kaye. It was not possible to issue an "original soundtrack album" of the film, because Decca Records controlled the soundtrack rights, but Clooney was under exclusive contract with Columbia Records. Consequently, each one issued a separate "soundtrack recording": Decca issuing Selections from Irving Berlin's White Christmas, while Columbia issued Irving Berlin's White Christmas. On the former, the song "Sisters" (as well as all of Clooney's vocal parts) was recorded by Peggy Lee, while on the latter, the song was sung by Rosemary Clooney and her own sister, Betty. The Clooney sisters' version, which was also released as a single, was the most popular recording of the song, charting in 1954.
The song was also made famous in the United Kingdom by sister act the Beverley Sisters.
A 2004 album of songs made famous by Rosemary Clooney, done by Bette Midler, included a version of the song done by Linda Ronstadt and Midler.
