J. & J. Kammen Music Company, commonly known as the Kammen Brothers, was a sheet music publishing company operated in Brooklyn, New York by Jack and Joseph Kammen from the 1920s to the 1970s. The company published Jewish music (including Klezmer and Yiddish theatre music) as well as non-Jewish music. They owned the rights to some well-known songs such as Bei Mir Bistu Shein. Their Klezmer Fake books were by far the most popular of their time, offering arranged interpretations of Jewish wedding repertoire for non-specialist musicians.
