Saturday Night (musical)

Saturday Night is a 1955 musical with music and lyrics by Stephen Sondheim and a book by Julius J. Epstein, based on the play, Front Porch in Flatbush, written by Epstein and his brother Philip.

The first professional musical written by Stephen Sondheim, Saturday Night was intended to open on Broadway in 1955; however, after the sudden death of its lead producer, the show was shelved. Sondheim instead made his professional premiere in 1957 as the lyricist for West Side Story.

Following a student production, Saturday Night was staged at the Bridewell Theatre, London in 1997 and then in Chicago in 1999 and Off-Broadway in 2000. The musical also ran in the West End in 2009.
