Side Show is a musical by Bill Russell and Henry Krieger (music) based on the lives of Daisy and Violet Hilton, conjoined twins who became famous stage performers in the 1930s.

Daisy and Violet Hilton were English-born entertainers, who were conjoined twins. They were exhibited in Europe as children, and toured the United States sideshow, vaudeville and American burlesque circuits in the 1920s and 1930s. They were best known for their film appearances in Freaks and the biographic Chained for Life (1951).
