Barbara Cook was an American actress and singer who first came to prominence in the 1950s as the lead in the original Broadway musicals Plain and Fancy (1955), Candide (1956) and The Music Man (1957) among others, winning a Tony Award for the last. She continued performing mostly in theatre until the mid-1970s, when she began a second career as a cabaret and concert singer. She also made numerous recordings.

Plain and Fancy is a musical comedy with a book by Joseph Stein and Will Glickman, lyrics by Arnold Horwitt, and music by Albert Hague. One of the first depictions of an Amish community in American pop culture, it includes a traditional barn raising and an old-fashioned country wedding. The musical ran on Broadway in 1955–56, and has been produced yearly at the Round Barn Theatre in Nappanee, Indiana since 1986.
